The Infrared Proximity Sensor (E18-D80NK) is a digital proximity sensor uses an infrared LED and receiver to determine the presence of an object within a specific distance
The best part of this sensor is that it contains both infrared and full spectrum diodes
SCL : VCC + 0
HC-SR04 ultrasonic module can offer non-contact distance sensing function
a permanent magnet or a combination of both
Sound Sensor (High Sensetivity) thermocouple The Infrared Proximity Sensor (E18-D80NK)Sound sensor module with analog and digital output. It works with supply voltage from 3. 3 V to 5. 3V. It allows you to detect not only the volume of the sound but also the identification of characteristic sound source, therefore you can distinguish the source of the sound. Adjust the on board potentiometer to adjust the sensitivity. The module output HIHG LOW when the voice is Lower higher than the threshold set by the potentiometer. Features:
