Monitor your soils water and temperature condition and improve irrigation scheduling
It’s easy to know your soil’s water and temperature condition with Monnit’s Soil Moisture Wireless Sensor. It provides a highly effective way to improve irrigation scheduling and efficiency. You’ll know when and where to water your crops, plants, or landscape from the data you gather.
See water tension to prevent water stress
The Soil Moisture Sensor measures soil water tension (matric potential) and temperature. With a resistive granular matrix element, you can optimize your tension parameters to determine the earliest indication of water stress and make sure you irrigate before it reaches that point. The unique element feature delivers consistent calibration without needing to recalibrate for every installation.
The Sensor also has a thermistor-based temperature element. Its readings will help you assess temperature -40°C to 125°C (-40°F to 257°F) and the moisture’s temperature compensation, eliminating the need to measure moisture every time the soil temperature changes.
Key features of our Soil Moisture Sensor include:
- Safe and durable in both hot and freezing temperatures
- Measure within a range of 0 to 240 centibar (cb) or kilopascal (kPa)
- Corrosion-resistant and made of high-grade stainless steel
- Internally compensated for commonly found salinity levels
- Easy to install and use compared to traditional tensiometers
- Includes a 5-ft. removable lead
The sensor’s moisture element is unique because it works similar to a plant’s root by measuring water tension in its hydrophilic fabric-covered matrix material rather than the surrounding soil.
The Soil Moisture Sensor has a removable soil moisture/temperature lead and a single sensor base. The sensor works best when you bury the lead or soil probe within or very close to a plant or tree root system. The sensor also works well in most soil types.
This sensor comes with an industrial battery included with the life of up to 7 years.
All industrial sensors are enclosed in a reliable, weatherproof NEMA-rated enclosure that are constructed for both indoor and outdoor use. These rugged enclosures protect the sensor circuitry against;
- Falling dirt
- Wind-blown dust
- Rain, sleet, snow, splashing water, and hose-directed water
- Ice formation on the enclosure
- Increased resistance to corrosion
Features
- Impressive wireless range of up to 1,200 feet through walls
- Frequency-hopping spread spectrum (FHSS)
- Improved interference immunity
- Improved power management for longer battery life
- Encrypt-RF® Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)
- Stores 2000 to 4000 readings if gateway connection is lost (non-volatile flash, persists through the power cycle)
- 10-minute heartbeats = ~ 22 days
- 2-hour heartbeats = ~ 266 days
- Over-the-air updates
