HC SR505 PIR SENSOR ARDUINO

arduino - PIR sensor always gives HIGH - Electrical ...

Mar 04, 2016· But when I test the output of the PIR , it gives always HIGH . I rotate sensitivity adjustment and time delay adjustment randomly to see any changes occur. I even cover the sensor with cloth so that It get's no infrared . still it gives high. I changed my sensor and bought a new one. This shows the same problem too. arduino code :
