Temperature Relay Circuit
This simple temperature relay circuit can be used to signal a fire or setpoint for temperature monitoring function. You need to adjust P1 so...
Make a Simplest Temperature Indicator Circuit
As we know that all semiconductors have this bad habit of changing its basic characteristics in response to ambient temperature changes. E...
Over-Temperature Switch
The output goes high when a preset temperature is exceeded. A fixed half-supply reference voltage feeds a reference...
Under-Temperature Switch
The reference current is fed from the supply voltage via Rl, to the inverting terminal, and the variable (noninver...
Simple Temperature Indicator
For the absolute measurement of temperatures, a thermometer is indispensable. However, in many situations, an ...
Temperature Controller
A thermistor (RI) is compared with a reference (R2) in a Wheatstone-bridge circuit. Comparator Ul"s output goes high...
Differential-thermometer
The differential thermometer uses two probes and shows the temperature difference betw-een them, rather than the exact temperature. ...
Temperature meter
TCA965 window discriminator IC allows the potentiometers RVl and RV2 to set up a window height and window width respectively. Rl and thermis...
Single-setpoint temperatre controller
The AD590 produces a temperature-dependent voltage across R (C is for filtering noise). Setting R2 produces a scale-zero voltage. For the Ce...
Digital temperature measuring
The output voltage of a thermocouple is converted into frequency measured by a digital frequency meter. The output thermocouple signal is pr...
Adjustable threshold temperature alarm
When Rl increases as temp decreases, the output of IC1 goes positive, turning on Ql. Ql conducts and causes Q2 to conduct, turning on the au...
PC thermometer schematic
This incredibly simple thermometer plugs on any free serial port. Does not make use of any programmable components as microcontrollers. It g...
Temperature limit Relay
This circuit, is basically a resistance ? sensing window switch, except that the ?resistor? takes the form of an NTC thermistor and the circ...
Limit Temperature Buzzer
The circuit is small regulatorof temperature, us warns for the increase of temperature. The control of temperature becomes from the thermist...
