How to use a HC-SR501 Sensor
Posted by Kelly M on
HC-SR501 is based on infrared technology, an automatic control module with high sensitivity and ultra-low-voltage operating mode, making it highly reliable to use. It is widely used in various auto-sensing electrical equipment, like battery-powered automatic controlled products. Wiring The HC-SR501 sensor operates at 5V to 20V, and the digital output pin gives out a HIGH or LOW signal depending on if the sensor detects any motions. Thus, the sensor can be used without connecting to a microcontroller and just by a power supply and a load. For instance, it can be connected to the power supply and a lightbulb. Then,...
