The 37-in-1 Sensor Modules Kit is a comprehensive, plug-and-play electronics suite designed for rapid prototyping with Arduino, Raspberry Pi, and ESP32. Featuring 37 individually PCB-mounted sensor and actuator modules, it eliminates complex breadboard wiring by utilizing standard pre-soldered 2.54mm header pins. Operating between 3.3V to 5V DC, the kit provides an array of digital, analog, and communication-bus interfaces (such as single-wire DHT protocol). It covers environmental metrics (DHT11 temperature/humidity, flame tracking), motion/tactile inputs (XY-axis joystick, vibration, tilt), optoelectronics (650nm laser, 38kHz IR transceiver, RGB LEDs), and load switching (5V relay capable of handling 250VAC/10A). This kit is highly optimized for STEM education, IoT development, and smart automation engineering.
