Z-Wave is a wireless communications protocol used primarily for residential and commercial building automation. It is a mesh network using low-energy radio waves to communicate from device to device, [2] allowing for wireless control of smart home devices, such as smart lights, security systems, thermostats, sensors, smart door locks, and garage door openers.
Similarly to DECT, ULE uses a dedicated radio frequency, outmatching other technologies, such as Zigbee, Z-Wave, Bluetooth and others in terms of stability. Primary application areas of ULE based wireless networks are for home automation, home security and climate control. Each of these application areas represent variety of dedicated devices.
The Air Quality Egg is an example of a low-cost, personal air pollution sensor. At one end of the scale, there are small, inexpensive portable (and sometimes wearable), Internet-connected air pollution sensors, such as the Air Quality Egg and PurpleAir. [ 9 ]
All of these sensors are used for a wide range of applications and can be found in industrial plants, refineries, pharmaceutical manufacturing, fumigation facilities, paper pulp mills, aircraft and shipbuilding facilities, hazmat operations, waste-water treatment facilities, vehicles, indoor air quality testing and homes.
The Air Quality Egg (AQE) is an Internet of Things platform and hobbyist device for crowdsourced citizen monitoring of airborne pollutants. The device won widespread recognition when it was named one of the best projects on Kickstarter in 2012, [ 1 ] and has been featured in a variety of media outlets. [ 2 ]
Millimeter wave (mmWave) sensing is a non-contact system of using mmWave radar sensors to measure movement, acceleration, and angles as small as a fraction of a millimeter. [1] This system requires a mmWave radar sensor to transmit and receive pulses of millimeter electromagnetic wave energy, detecting targets and motion from the reflections it ...
