2. Smart thermostat - Wikipedia

   en.wikipedia.org/wiki/Smart_thermostat

   One issue with using a smart thermostat is the unreliability of the motion sensor. One of the main features of the smart thermostat is the ability to change the temperature when the sensor in the thermostat does not sense an occupant. The only sensor that is used though is the sensor in the thermostat.

3. Thermostat - Wikipedia

   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. Electronic thermostats have an electronic equivalent. [5] When higher control precision is required, a PID or MPC controller is ...

4. HVAC control system - Wikipedia

   en.wikipedia.org/wiki/HVAC_control_system

   HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. [1] Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g. start the ...

5. Temperature control - Wikipedia

   en.wikipedia.org/wiki/Temperature_control

   Temperature measuring and controlling module for microcontroller experiment. Temperature control is a process in which change of temperature of a space (and objects collectively there within), or of a substance, is measured or otherwise detected, and the passage of heat energy into or out of the space or substance is adjusted to achieve a desired temperature.

6. AVR microcontrollers - Wikipedia

   Raven peripherals resemble the Butterfly: piezo speaker, DataFlash (bigger), external EEPROM, sensors, 32 kHz crystal for RTC, and so on. These are intended for use in developing remote sensor nodes, to control relays, or whatever is needed. The USB stick uses an AT90USB1287 for connections to a USB host and to the 2.4 GHz wireless links.
