Measures pressure in the atmosphere.Features:Size: approx. 3.6mmx 3.8x 0.93mmAccurate, the absolute minimum accuracy can reach 0.03 hPa, and power consumption is extremely low, only 3 μAPinouts are clearly marked on reverse side of board..
PIR sensors often referred to as, Passive Infrared or IR motion sensors, enable you to sense motion. Everything emits a small amount of infrared radiation (IR), and the hotter something is, the more radiation it emits. PIR sensors are able to detect a change in average IR levels of their detection z..
KY-038 microphone sound sensor module for basic sound level detection, featuring an electric condenser microphone. There are 2 LEDs on board, one is for power and the other corresponding to the digital output. The sensor outputs both an analog and digital output.Pinout:DO: Digital Output (compa..
