Monnit wireless grains per pound sensors measure the mass in grains of H2O in otherwise dry air.
Put simplistically, the measurement is the weight of water in air.
This sensor uses a calibrated humidity sensor to obtain the absolute humidity at the current temperature and converts that value into the Grains per Pound measurement displayed.
User customization allows you to set the frequency of readings and the ability to set conditions for alerts by SMS text, email or voice call.
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.
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
