YES-H-ATRH-01 is a rugged, accurate Temperature/RH probe manufactured with high precision sensing elements, ideal for long-term, unattended applications. The probe uses a capacitive polymer H chip to measure RH and MEMS to measure temperature. To reduce the current drain, power can be supplied to the YES-H-ATRH-01 only during measurement when the sensor is connected to the data loggers switched suppy terminal. For optimum results, the YES-H-ATRH-01 should be recalibrated annually. This sensor integrate sensor elements plus signal processing in compact format and provide a fully calibrated digital output, guarantees excellent reliability and long term stability. Both sensors are seamlessly coupled to a 14 bit analog to digital converter and a serial interface circuit. This results in superior signal quality, a fast response time and insensitivity to external disturbances (EMC).
YES-H-RS radiation shield is recommended to be used when the sensor is exposed to sun light.
