Out of stockDigital Multimeter Small Yellow Color LCD AC DC Measuring Voltage Current
[Measuring Instruments] A multimeter or a multitester, also known as a VOM (Volt-Ohm meter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter would include basic features such as the ability to measure voltage, current, and resistance. Analog multimeters use a microammeter whose pointer moves over a scale calibrated for all the different measurements that can be made. Digital multimeters (DMM, DVOM) display the measured value in numerals, and may also display a bar of a length proportional to the quantity being measured. Digital multimeters are now far more common than analog ones, but analog multimeters are still preferable in some cases, for example when monitoring a rapidly-varying As the name suggests it is the multifunction device for all your testing need for daily work. When testing DC voltage, AC voltage, DC current, resistance, diode, buzzer, and battery, connect the red test lead to “VΩmA” jack and black test lead to “COM” jack, whereas When you need to test the current more than 200mA, connect the red test lead to “‘ 10A≡” jack and black test lead to “COM” jack. And When while testing the temperature, connect the temperature probe to “VΩmA” jack or “COM” jack. When testing the magnifying ratio of the transistor, turn the switch to hFE position and connect the transistor to the eight hole jack available in blue color. For the Square wave output, the frequency is 50Hz, the voltage is approximately 3Vp-p. The output jack is “VΩmA” and “COM” Description Table: Features : Small size makes it comfortable in many areas Brand new product. Good for newbies with basic knowledge of VI.

0.36inch 4.5-30V Two Wire DC Voltmeter
[Ammeter and Voltmeter] This is tiny and compact digital voltmeter with red LED Display. 0.36inch 4.5-30V Two Wire DC Voltmeter Red Panel requires only a few minutes of configuration and is as simple as directly connecting wires to the source you want to measure and seeing the LED blink!!!! The red wire is to connect to the positive pole, the black wire is to connect to the negative pole. No need to worry even if there is any connection mismatch of the wires, the electric circuit won’t be a boom because it features reverse polarity protection. This voltmeter doesn’t need external drive working power, it can work with measuring voltage, the working voltage’s range is 3.5-30V. To reach the best measurement accuracy, this voltmeter will automatically move the decimal point’s position according to the different measuring voltage. When it measures the voltage below 10V, it will display two places after the decimal point. When it measures the voltage above 10V, it will display one place after the decimal point. This voltmeter can be used to measure the storage battery’s voltage in motorcycles and cars and also can grasp the storage battery’s status. It also can be used to measure other voltage. 30V is the voltmeter’s maximum operating limited voltage, please leave enough margin when working, to avoid voltmeter’s permanent damage because of an electrical spark, power supply ripple, or other too high abrupt change of voltage. Very bight and decent LED Display is ready to measure the dc voltages in the range of 4.5V to 30V. Connections : Red Wire: source +ve terminal. Black Wire: Source -ve terminal. Note: The display weight and Dimensions may have ±2% error. We also have the same module in two different colors as(click on the color name below for more information) Features : Very small and lightweight voltmeter module. Very handy and easy to use. Red/Blue/Green/Yellow LED display. Don’t need the external power supply because it is a self-powered version of this display. Best operates in the working voltage range of 5V to 24V 100% Brand new and high quality. Package Includes : 1 x 0.36inch 4.5-30V Two Wire DC Voltmeter Red/Blue/Green/Yellow

[Li-Ion Capacity Indicator] The LiPo Battery Voltage Checker 1S-8S with Buzzer is a quality product available and a special design to measure and display the voltage of LiPo battery packs. This voltage checker can measure the voltage of the battery pack as well as the voltage of every single cell of the battery pack. This unit also features a handy built-in LED display that will show the voltage of each cell followed by the overall voltage of the pack. Don’t risk your model by flying on depleted batteries, at this price piece of mind flying can’t be any cheaper! Simply connect the battery balance plug to the leads of this voltage checker, it will show the instant voltage of each cell one by one ending with displaying the voltage of the total pack. The Li-PO Voltage Checker 1S-8S with Buzzer Alarm is equipped with loud twin piezo alarms which will notify you once your cells reach a low voltage or user defined voltage. You can customize the alarm to sound at a voltage between 2.7v-3.8v per cell in 0.10v increments. It has a mode button at the top for setting the desired voltage value. Features : Input: 1S-8S Battery Battery type: Lipo/LiFe/Li-ion/LiMn It has a Buzzer Alarm for low voltage indication. Useful for measuring each cell voltage. It has a mode button at the top for setting the desired voltage value. Package Includes : 1 x LiPo Battery Voltage Checker 1S-8S with Buzzer
Out of stockDigital LDR Module
[Light Sensors] The Digital LDR Module is used to detect the presence of light / measuring the intensity of light. The output of the module goes high in the presence of light and it becomes low in the absence of light. The sensitivity of signal detection can be adjusted using the potentiometer. Use it to detect the light brightness in your environment and decide to switch OFF or ON light? Or maybe to adjust the brightness of the LED of your house? You can adjust the threshold (sensitivity) of the digital output by tuning the onboard variable resistor (potentiometer). Simple usage as it is the digital output, so you will know is the light present and decide what to do with it. It comes with an M3 mounting hole for ease of attaching it to an object. Onboard, it provides an LDR, high sensitivity and commonly being used for light detection. The module comes with a power LED and a status LED as an indicator. LDR Module Photosensitive resistor module most sensitive to environmental light intensity is generally used to detect the ambient brightness and light intensity. Features – LM393 based design. Can detect ambient brightness and light intensity. Adjustable sensitivity (via blue digital potentiometer adjustment). Output Digital – 0V to 5V, Adjustable trigger level from preset. LEDs indicating output and power. Operating Voltage: 3.3V to 5V DC. Operating Current: 15ma. How it works 1. Module light conditions or light intensity reach the set threshold, DO port output high when the external ambient light intensity exceeds a set threshold, the module D0 output low; 2. Digital output D0 directly connected to the MCU, and detect high or low TTL, thereby detecting ambient light intensity changes; 3. Digital output module DO can directly drive the relay module, which can be composed of a photoelectric switch. Pin details VCC ↔ 3.3V to 5V DC. GND ↔ Ground. DO ↔ Digital Output.
HC-SR04-Ultrasonic Range Finder
[Ultrasonic Sensor] This HC-SR04-Ultrasonic Range Finder is a very popular sensor that is found in many applications where it requires measuring distance and detecting objects. The module has two eyes like projects in the front which forms the Ultrasonic transmitter and Receiver. The HC-SR04 ultrasonic sensor uses sonar to determine the distance to an object like bats or dolphins do. This Ultrasonic Sensor module is a transmitter, a receiver, and a control circuit in one single pack!! It has very handy and compact construction. It offers excellent range accuracy and stable readings in an easy-to-use package. Its operation is not affected by sunlight or black material like Sharp rangefinders are (although acoustically soft materials like cloth can be difficult to detect). The Trigger and the Echo pins are the I/O pins of this module and hence they can be connected to the I/O pins of the microcontroller/Arduino. When the receiver detects the return wave the Echo pin goes high for a particular amount of time which will be equal to the time taken for the wave to return back to the sensor. Ultrasonic Ranging Module HC-SR04 provides 2cm-400cm non-contact distance sensing capabilities, Ranging accuracy up to 3mm. Wiring +5V(positive) Trig(control) Echo(receive) GND(negative) Features : Measures the distance within a wide range of 2cm to 400cm Stable performance Accurate distance measurement High-density Small blind distance Package Includes: 1 x HC-SR04-Ultrasonic Range Finder
