Wired temperature and humidity sensor with digital output

Reference AR003928

Delivery in 3 to 5 weeks

Temperature and relative humidity sensors are designed to measure the temperature and relative humidity of the air in spaces protected against the ingress of water. The sensors consist of a polyamide housing containing a temperature and relative SHT30F probe and an input cable with PVC insulation. Free air access is guaranteed to the temperature and relative humidity sensor, which ensures its very rapid response to changes in the two measured variables. Communication with the sensor is ensured by means of an I2C bus with a communication speed of up to 1 MHz and with the possibility of up to two separate and user-selectable addresses.

GTH161R data sheet | Wired temperature and humidity sensor with digital output

Product features Wired temperature and humidity sensor with digital output

Recommended operating conditions to ensure the most accurate output values:

- ambient temperature around the sensor: 5 to 60 ° C

- relative ambient humidity: 20 to 80%

- atmospheric pressure: 87 to 106 kPa

The temperature and relative humidity sensor is protected by a special PTFE membrane, which increases the resistance of the sensor against the impact of dust and water, ensures the minimum level of protection IP 65 according to EN 60759. as 'amended and allows the sensor to be used in severe conditions with a greater occurrence of dust or water spray.

The temperature and relative humidity sensors are designed to operate in chemically non-aggressive environments; their mode of use must be chosen according to the temperature and the chemical resistance of the case and the power cable.

Warnings and Restrictions - Sensors should not be used to measure the temperature in areas:

  • Or the specified technical parameters and operating conditions are not met
  • Possible mechanical impact on the sensor
  • Explosion risk area
  • Chemically aggressive environment
  • where the sensor could be exposed to permanent immersion in a liquid
  • where the sensor could be exposed to the impact of electrostatic discharge (ESD)

Failure to comply with the stated recommendations and long-term exposure to conditions outside the recommended operating conditions will have a negative impact on the measurement accuracy and the service life of the temperature sensor. Especially at high humidity, there may be an offset of the RH output signal (for example, + 3% RH after 60 hours kept above the value of 80% RH). When the standard temperature and humidity range is restored, the sensor automatically returns to the calibrated state.

ACCESSORIES:

- different connector variants --- HIRSCHMANN, LEMO, MOLEX, JST, etc.
