Choosing a temperature sensor for an IoT device? Compare thermistors, RTDs, thermocouples, and digital sensors against your measurement range, accuracy target, response time, and operating conditions. Assess interface and power trade-offs for your controller, then leave with a shortlist, the reasons each option fits, and the open questions to check before choosing a part.

What it writes
- Side-by-side sensor trade-off table
- Shortlist ranked against your requirements
- Temperature-reading troubleshooting checklist
How to use it
Include the temperature range, accuracy target, response time, and whether the sensor contacts air, liquid, or a surface. Add your controller and power budget so the comparison can account for interface and battery constraints.
What you bring
- Measurement range and accuracy target
- Operating conditions and power budget
- Controller, interface, or candidate part numbers
- Know the device’s measurement conditions
A good fit for
- Selecting a sensor for a battery-powered outdoor monitoring device
- Comparing digital sensors and thermistors for a compact appliance
- Checking interface and range fit before a hardware design review
Ways to start
A few requests this Agent can handle.
I need to measure -10 to 80°C inside a battery-powered greenhouse monitor. Compare digital sensors and thermistors for accuracy, response time, and power.
Compare these options for an ESP32 board: a TMP117 and a 10k NTC thermistor. I need ±0.5°C accuracy from 15 to 40°C and low standby power.
My thermistor reading jumps when a small motor starts. The divider uses a 10k resistor and a 3.3V ADC; what circuit issues should I check?
Good to know
This workspace provides text assistance.
- Safety-critical designs without qualified engineering review
- Cannot check current manufacturer datasheets or part availability
- Cannot test sensors or diagnose hardware from measurements alone
