.. too good to let pass by. Figure 1 shows the new circuit I cooked up, (loosely) based on Jim’s recipe. Figure 1. ∆V BE sensor Q1 is programmed via R1 for desired setpoint temperature in Kelvin = R1/100 = 312 K = 39 C for R1 = 31.2k. ...
.. analog compensation of the thermally induced errors inherent in many circuits. For example, a negative-sloped temperature sensor could compensate for an increase in amplifier bias current resulting from a rise in temperature. Some ...
.. if the application involves conversion of a ratiometric signal proportional to +6 V such as provided by a resistive sensor (e.g., thermistor), then U2 and friends should be omitted, U1 pin 2 connected to 6 V, and C2 reduced to 1.6 ...

.. detectors), and thermistors produce a resistance that’s proportional to force or temperature. If you measure a sensor’s resistance, you can calculate the physical parameter. Circuits such as resistance bridges can help ...
.. recent EDN design ideas, we’ve seen thermostat designs that meld the functions of sensor and heater into a single device: FET, BJT, or even a simple length of fine gauge copper wire. A virtue ...
