You can add various temperature probes till iBLOPPER MATE. You can both use the header as connection (ESP 32 DevKit ver 1) or cable by “Grove – 4-pin 2mm – female wires 2.54mm” for M5 S3 Atom LCD, please see diagram for details under supported ESP boards.
The temperature probe is mostly needed for the “iBLOPPER mode”. Especially, to make use of the Temeprature Controll system, but if only using in connection with eHydrometers the temperature will come form these.
The most suited is to use the cable connection and if you use “Grove – 4-pin 2mm – female wires 2.54mm” it is the white cable for the temperature signal. We have tested with the following:
- Iduino SE042
- DFRobot Gravity – DS18B20 temperature sensor
- DS18B20 temperature sensor + wire – Iduino SE029
- DS18B29 1 meter cable + 4.7k resistor
- Ky-001 or Keyes DS18B20 Temperature Sensor Module
