The integrated circuit sensor may come in a variety of interfaces — analogue or digital; for digital, these could be Serial Peripheral Interface, SMBus/I 2 C or 1-Wire.. In OpenBSD, many of the I 2 C temperature sensors from the below list have been supported and are accessible through the generalised hardware sensors framework [3] since OpenBSD 3.9 (2006), [4] [5]: §6.1 which has also ...
In September 2013, Variable Inc. announced the release of an Android-compatible NODE+ wireless sensor platform. [16] The device had been only iOS compatible. NODE+CO 2 , a carbon dioxide sensing module, one of six different gas sensors in the OXA sensor family, raised $26,046 on Kickstarter, $1,046 over its goal on December 31, 2013.
The study compared a standard ("reactive") smart thermostat and the multiple sensor system to a manual thermostat. The study concluded that a reactive smart thermostat with just on sensor saves, on average, 6.8% of energy consumption, while the multiple sensor system saved an average of 28% of energy consumption.
Turning off exactly at the setpoint will cause actual temperature to exceed the desired range, known as "overshoot". Bimetallic sensors can include a physical "anticipator", which has a thin wire touched on the thermostat. When current passes the wire, a small amount of heat is generated and transferred to the bimetallic coil.
Wireless sensor networks (WSNs) refer to networks of spatially dispersed and dedicated sensors that monitor and record the physical conditions of the environment and forward the collected data to a central location. WSNs can measure environmental conditions such as temperature, sound, pollution levels, humidity and wind.
The self-test feature can be used a maximum of 60 times for optical sensors and 100 times for heat sensors, which equates to an expected life of up to 14 years of optical detection self-testing, and 20 years of heat detetection self-testing, with an expected maximum of 4 self-test and 4 manual tests a year, before the detectors need to be replaced.

A Fixed Threshold Detector triggers an alarm when a specific temp threshold is reached or exceeded. This type of detector is generally less sensitive to rapid temperature fluctuations, making it more suitable for areas like large, industrial kitchens where ovens or other heat-producing equipment are frequently in use.
