Review on ๐ก๏ธ DS18B20 Waterproof Digital Temperature Sensor with Adapter Module for Arduino - GAOHOU 2 PCS by Nick Cleary
Works well for telescope autofocus
I bought these for the Arduino Nano telescope focus control. I haven't tested the accuracy of the sensors versus a stand alone thermometer as I only need to know temperature changes. For my purposes they work very well.
- With a load resistor on the board, the adapter module can be directly connected to most microcontrollers, widely used for temperature control in aquarium, equipment, machinery and greenhouse.
- So far so good
