Beskrivning

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.
