3V 100mA LED Filament 45mm COB Edison Bulb Filament
[COB LED] The 3V 100mA LED Filament 45mm is a flexible COB LED light source designed for decorative lighting, Edison bulb restoration, DIY lamps, and creative illumination projects. Available in a variety of colors, it delivers bright and uniform light output while maintaining low power consumption. In addition, the filament provides 360-degree illumination, closely replicating the appearance of traditional Edison-style incandescent filaments. As a result, it is widely used in decorative bulbs, custom lighting fixtures, model lighting, art installations, and creative electronics projects. Because of its flexible substrate design, the filament can be slightly bent to fit custom enclosures and unique lighting arrangements. Furthermore, it produces minimal heat during operation, making it safe for compact and enclosed lighting applications. The advanced COB LED structure ensures consistent brightness, excellent efficiency, and long service life. Moreover, the solderable metal terminals allow quick integration into DIY electronics and lighting projects. 🔹 Key Features Available in multiple colors Bright and uniform light output COB LED filament design Low power consumption Excellent energy efficiency Minimal heat generation 360° illumination pattern Lightweight and compact structure Easy solderable metal terminals Long operational life 🔹 Technical Specifications Product Type: COB LED Filament Operating Voltage: 2.8V to 3.2V DC Rated Voltage: 3V DC Forward Current: 100mA (Maximum) Power Consumption: Approximately 0.3W Brightness: Approximately 80–100 Lumens per Watt Filament Type: COB (Chip-on-Board) LED Filament Base Material: Flexible Polymer Substrate Connection Type: Solderable Metal End-Caps led Length: 45mm Total Length: 55mm Filament Diameter: Approximately 2.0mm Terminal Size: Approximately 2mm × 2mm Weight: Less than 1g Available Colors: Warm White, Cool White, Red, Blue, Green (subject to availability) 🔹 Mechanical Specifications Filament construction Durable polymer substrate Highly resistant to mechanical shock Lightweight design Easy soldering connection terminals Suitable for custom lamp and lighting assemblies 🔹 Applications This LED filament is suitable for: Edison bulb repair and replacement Decorative LED lamps Custom lighting fixtures Battery-powered lighting projects Art installations Scale models and dioramas Display and showcase lighting Wearable electronics DIY electronics projects Creative lighting applications 🔹 Package Includes 1 × 3V 100mA LED Filament 38mm (Selected Color)

Out of stockMAX30102 Pulse Oximeter Heart Rate Sensor Module
[Proximity Sensor] MAX30102 is a sensor that combines a pulse oximeter and a heart rate monitor. It’s an optical sensor that measures the absorbance of pulsating blood through a photodetector after emitting two wavelengths of light from two LEDs – a red and an infrared one. This particular LED colour combination is designed to allow data to be read with the tip of one’s finger. It is fully configurable through software registers and the digital output data is stored in a 16-deep FIFO within the device. It has an I2C digital interface to communicate with a host microcontroller. The pulse oximetry subsystem in MAX30102 consists of ambient light cancellation (ALC), 16-bit sigma-delta ADC, and a proprietary discrete-time filter. It has an ultra-low-power operation which makes it ideal for battery-operated systems. MAX30100 operates on a supply in the range of 1.8 to 3.3V. It can be used in wearable devices, fitness assistant devices, medical monitoring devices, etc. This sensor works on 3.3V Devices directly. You can connect it to 3.3V devices like ESP8266, ESP32, etc. directly. To use it with the Arduino UNO, Mega, Nano, etc. use a level shifter in between. Else I2C connection will not work. Features Heart-Rate Monitor and Pulse Oximeter Sensor in LED Reflective Solution Tiny 5.6mm x 3.3mm x 1.55mm 14-Pin Optical Module Integrated Cover Glass for Optimal, Robust Performance Ultra-Low Power Operation for Mobile Devices Programmable Sample Rate and LED Current for Power Savings Low-Power Heart-Rate Monitor (< 1mW) Ultra-Low Shutdown Current (0.7µA) Fast Data Output Capability High Sample Rates Robust Motion Artifact Resilience High SNR -40°C to +85°C Operating Temperature Range
