Circuit for Temperature Sensor
Budget: ₹12,500 – ₹37,500 INR
Design circuit diagram
Generate BOM
PCB Design & layout with Gerber
Project
Design a circuit that will output varying (0-5 VDC) for variation in temperature, with temperature sensing range -50C to +80C or wider.
We would like to use the thermistor as per picture attached. It seems to be a NTC thermistor temperature probe with a diode. It has 2 wires, so it is not a PT100. Also, it seems to have a negative temperature coefficient. Diode drop is about 0.5V. Resistance measured at about 20C, when multimeter is at 20K position shows 1.95 and when multimeter is set to 200K, then the value changes to 16.1. WHAT IS THIS?
