MONNIT INDUSTRIAL WIRELESS GRAINS PER POUND SENSOR
Availability: In stock
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.
The standard version of this sensor is powered by two replaceable 1.5 V AA sized batteries (included with purchase). This sensor is also available with a line power option. The line powered version of this sensor has a barrel power connector allowing it to be powered by a standard 3.0 – 3.6 V power supply (Included with Line Power option upgrade). The line powered version also uses two standard 1.5 V AA batteries as backup for uninterrupted operation in the event of line power outage.
Power options must be selected at time of purchase, as the internal hardware of the sensor must be changed to support the selected power requirements.
- Scientific grade sensor.
- Measures the weight of water in air.
