Differential temperature measurement is a handy way to quantify the performance of heatsinks, thermoelectric coolers, and thermal control in electronic assemblies. Figure illustrates an inexpensive design for a high-resolution differential thermometer utilizing the ∆VBE effect to make accurate measurements with ordinary uncalibrated transistors as precision temperature sensors...

Hotwire thermostat Using fine copper wire
Hotwire thermostat: Using fine copper wire as integrated sensor and heater for temperature control
03.04.2024 Circuits

Conventional thermostats are based on separate temperature sensor and heater devices with means for feedback between them. But in some recent EDN design ideas we’ve seen thermostat designs that meld the functions of sensor and heater into a single active device...
