Comet W7811

The device measures the temperature and humidity from an external probe on the cable. In comparison with sensor W3811 the sensor W7811 is additionally equipped with an internal sensor of atmospheric pressure. The sensor is characterized by a simple and compact design with the possibility of installation directly into the measured space. Model with external cable probe is also suitable for measurements in areas where the risk of poor reception sigfox. The probe can be placed at the measurement point and the device itself where is able to reach a better signal. The probe length must not exceed 30 meters. The probe can be used with a suitable sensor cap even in more demanding conditions.
