| − | The ESP module can read a Dallas DS18b20 sensor using the Dallas OneWire protocol.
| |
| | | | |
| − | The Dallas sensor needs to be connected to a configurable GPIO on the ESP module. In case you have a simple ESP-01 module, it's best to use the GPIO-2 pin.

| |
| − | The Dallas sensor can be connected directly to an ESP module. It only needs a 4k7 resistor connected between VCC and the GPIO datapin.
