MQ-2 Gas Sensor Module For H2, LPG, CH4, CO, Smoke or Propane Detector Module
[Gas and Dust Sensor] MQ-2 Gas Sensor Module The MQ-2 Smoke LPG Butane Hydrogen Gas Sensor Detector Module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke, or Propane. Due to its high sensitivity and fast response time, measurements can be taken as soon as possible. The sensitivity of the sensor can be adjusted by the potentiometer MQ-2 gas sensor using gas-sensitive material is to be clean air in the lower conductivity of tin oxide (SnO2). When the sensor when flammable gases are present in the environment in which the conductivity of the sensor with an increasing concentration of combustible gas in the air increases. Package Includes: 1 x MQ2 Gas Sensor Module
MQ-5 Methane LPG Liquid Propane Gas Sensor Module
[Gas and Dust Sensor] The Simple MQ-5 Methane LPG Liquid Propane Gas Sensor Module is a great way to add basic gas sensing to your project at a reasonable price. TheMQ-5 Methane LPG Liquid Propane Gas Sensor Module particulate sensor uses a Buzzer to sense any detected material that is even present in the air! This MQ-5 Methane LPG Liquid Propane Gas Sensor Module is widely used in gas leakage detecting pieces of equipment in family and industry, are suitable for detecting LPG, natural gas, town gas, avoid the noise of alcohol and cooking fumes and cigarette smoke The MQ5 ( MQ-5 ) is used in gas leakage detecting equipment in consumer and industry applications, this sensor is suitable for detecting LPG, natural gas, coal gas. Avoid the noise of alcohol, cooking fumes, and cigarette smoke. The sensitivity can be adjusted by the potentiometer. The sensitive material of the MQ-5 gas sensor is tin Oxide (SnO2), which with lower conductivity in clean air. When the target combustible gas exists, The sensor’s conductivity is higher along with the gas concentration rising. Please use a simple electro circuit, Convert the change of conductivity to the corresponding output signal of gas concentration. MQ-5 gas sensor has a high sensitivity to Methane, Propane, and Butane, and could be used to detect both Methane and Propane. The sensor could be used to detect different combustible gas especially Methane, it is with low cost and suitable for different application Connections VCC ↔ 2.5V ~ 5.0V GND ↔ ground Aout ↔ MCU.IO (analog output) Dout ↔ MCU.IO (digital output) Note: Buzzer is not included in this package, you have to buy it separately. Features : High sensitivity to LPG, natural gas, town gas. Small sensitivity to alcohol, smoke. Stable and long life. Simple drive circuit. Fast response. Package Includes : 1 x MQ-5 Methane LPG Liquid Propane Gas Sensor Module

60/40 Solder Wire 50g 22 SWG Tin Lead Soldering Wire for Electronics Repair
[Soldering Tools] The 60/40 Solder Wire 50g (22 SWG) is a high-quality soldering wire specially designed for professional electronics manufacturing, PCB assembly, electrical maintenance, and DIY repair work. Manufactured using a 60% Tin (Sn) and 40% Lead (Pb) alloy, it offers excellent electrical conductivity, mechanical strength, and easy solderability. The solder wire provides excellent wetting performance by reducing oxidation during soldering, allowing it to flow smoothly over copper pads, component leads, and electrical terminals. As a result, it produces bright, strong, and durable solder joints with minimal residue. Because of its 22 SWG wire diameter, the solder wire is ideal for general-purpose soldering, including PCB assembly, cable joints, connectors, switches, LEDs, and electronic components. Furthermore, it melts quickly, produces very little smoke and spatter, and provides excellent bonding performance. This solder wire is suitable for both beginners and professional technicians using standard soldering irons and soldering stations. 🔹 Key Features 60% Tin / 40% Lead alloy 22 SWG solder wire Fast melting characteristics Excellent solderability Bright and strong solder joints Low residue after soldering Minimal smoke and spatter High electrical conductivity Ideal for electronics and electrical repairs Long shelf life 🔹 Technical Specifications Product Type: Tin Lead Solder Wire Alloy Composition: 60% Tin (Sn) / 40% Lead (Pb) Wire Gauge: 22 SWG Approximate Wire Diameter: 0.71 mm Net Weight: 50g Melting Temperature: Approx. 183°C – 190°C Color: Silver Application: Manual Soldering Suitable For: Electronics & Electrical Components 🔹 Applications This solder wire is suitable for: PCB assembly PCB repair Mobile phone repair Electronic circuit repair Arduino projects Robotics projects Electrical wiring LED lighting repair Connector soldering DIY electronics Hobby projects Laboratory applications 🔹 Package Includes 1 × 60/40 Solder Wire 50g (22 SWG)
