Antminer S19 plus hash board troubleshooting for temperature sensing circuit

If the ambient temperature or hash board temperature is too high, Antminer S19+ will stop running. This is because a temperature sensing circuit is installed on each hash board to collect the temperature parameters of the hash board in real time. There are 4 temperature sensor chips in the temp sensing circuit of S19+ the hash board, and these chips are powered and controlled by the PIC chip. This lesson will explain in detail the working principle and voltage measurement about the temp sensor circuit.
