We can adjust delay time to Set how long the output remains high after detecting motion.... Anywhere from 5 seconds to 5 minutes. Similarly sensitivity adjusts the range from 3 to 7 meters. Retrigger setting jumper is to set for single or repeatable jumpers.
LM35 is an integrated-circuit temperature device with an output voltage linearly proportional to the centigrade temperature. As LM35 is not calibrated in Kelvin, user does not require to subtract large constant voltage from the output to obtain convenient centigrade scaling.
