Anyone have any experience using a DS18B20 temperature sensor? I would like to know if is possible to use with the bolt wifi module
The DS18B20 temperature sensor is a one wire digital temperature sensor. This means that it just requires one data line to communicate with your ESP32.it is not possible to use with bolt wifi module.
as @akkasagar5 said it is not easy to use this sensor with Bolt, but you can use an Arduino or ESP32 to collect data from the sensor and then link it to bolt WiFi module to upload it to cloud.
