The Monnit Wireless Resistance Sensor outputs the resistance across a load. It is programmed to sleep for a user-given time interval (heartbeat) and then wakeup, send power to the load resistor, wait for it to stabilize, and convert the analog data, mathematically compute the resistance and transmit the data to the gateway, where it is then logged into a cloud service. The user can configure defined thresholds and have the system alert on threshold breaches. Data is recorded in Ohms.

Product Description

The Monnit Wireless Resistance Sensor outputs the resistance across a load. It is programmed to sleep for a user-given time interval (heartbeat) and then wakeup, send power to the load resistor, wait for it to stabilize, and convert the analog data, mathematically compute the resistance and transmit the data to the gateway, where it is then logged into a cloud service. The user can configure defined thresholds and have the system alert on threshold breaches. Data is recorded in Ohms.

Monnit Industrial Sensors come in an IP65, NEMA 4X, CE rated, sealed, and weatherproof enclosure. They are powered by a single, replaceable, Industrial grade 3.6 V battery (included).

An optional solar powered version is also available. The solar powered version includes a Lithium Iron Phosphate rechargeable battery in conjunction with a solar power cell to keep the battery charged and at optimal capacity. If there is no light present at the solar cell, the battery alone could continue to power the sensor for up to 5 years.



Product Features
