Temperature Sensors Frequently Asked Questions

How does a Honeywell 5800PIR Work?
By using passive infrared (PIR) technology, the 5800PIR is able to detect the presence of intruders. The device is activated whenever a change in infrared energy is detected, signaling that an intruder is present. The pulse count of the 5800PIR can also be changed in order to adjust its sensitivity.
