For that purpose, an imaging IR sensor is required. PIR sensors are commonly called simply "PIR", or sometimes "PID", for "passive infrared detector". The term passive ...
Occupancy sensor types include: PIR sensors, which work on heat difference detection, measuring infrared radiation.Inside the device is a pyroelectric sensor which can detect the sudden presence of objects (such as humans) who radiate a temperature different from the temperature of the background, such as the room temperature of a wall.
In March 2016, HomeSeer released a line of Z-Wave Plus lighting products. [19] The line included the HS-WS100+ wall switch, HS-WD100+ wall dimmer, HS-WA100+ wall accessory (for 3-way circuits), HS-PD100+ lamp module, HS-PA100+ appliance module and HS-DTA19+ smart light bulb. In September, a Z-Wave motorized water valve was released.
PIR sensors identify abrupt changes in temperature at a given point. As an intruder walks in front of the sensor, the temperature at that point will rise from room temperature to body temperature and then back again. This quick change triggers the detection. PIR sensors designed to be wall- or ceiling-mounted come in various fields of view ...
