The company’s wireless sensors are available in a variety of form factors (e.g. zone, outdoor, duct) and for measuring different environmental variables (e.g. temperature, humidity, electricity/gas/water, voltage). The sensors are typically battery-powered with a life of 3 to 8 years, depending on transmission intervals. Optionally, sensors can be line-powered, using a small switching power supply that fits into a standard gang box. When a sensor detects the presence of a power supply, it will automatically also function as a repeater/router.
