Supplier information

SHT30, the whole is made of glue and waterproof treatment, to prevent condensation and cause short circuit damage to the sensor. Onboard 10K pull-up resistor and 100nF filter capacitor. The sensor PCB board is encapsulated in the protective cover of the PE cylinder, and it is led out through a 30cm 4PIN 24 electronic wire, and the interface is HY2.0-4P (2.0 with lock).

In order to prevent the water molecules inside the sheath from condensing into water when the ambient temperature is lowered, which causes the circuit board to be short-circuited or the sensor is damaged, we have applied glue to the circuit board and potted the mouth of the sheath. No interference to the measured value.

  • I²C address: 0X44
  • Connector type: HY2.0-4P (2.0 with lock)

The SHT30 has 2 user selectable I2C addresses; however, on the module this connection is fixed, so that the only I²C address is 0x44. Use the TCA9548A multiplexer to connect up to 8 of these modules to a single I²C bus - which has the added advantage of voltage level conversion.
