ZigBee module with 2 NTC inputs and 2 digital inputs
This device may be configured to manage alarm thresholds when exceeding maximum or minimum levels of temperature. It is also possible to adjust the sampling and data transmission rate to improve battery life. This device can perform data transmissions automatically and immediately (regardless of configured sampling rate) in order to signal a status change in one of the two digital inputs.
