Electronic Sensors for Arduino, ESP32 & Raspberry Pi

Sensors bridge the physical world and computational logic. Whether detecting obstacles with ultrasonic soundwaves, monitoring atmospheric humidity with resistive-capacitive elements, or measuring ambient light with photodiodes, our sensors feature standardized 3-pin and 4-pin headers (VCC, GND, Signal) compatible with both 3.3V and 5V microcontrollers.
