Wireless soil moisture and temperature logger

Wireless soil moisture logger is used to measure the amount of water in the soil. The sensor measures soil moisture levels and notifies of a sharp decrease or increase in the amount of water in the soil. The devices are powered by a battery that ensures their maintenance-free operation for a period of at least ten years.  The device comes in IP67 enclosure that protests it against the damage caused by water and dust.  The logger is equipped with an external Watermark soil moisture probe 3 m long and a temperature probe – 3 m.

Efento NB-IoT sensors transmit the data over cellular network (Narrowband IoT) and do not require any additional devices (router, gateway, etc.). Sensors are also equipped with Bluetooth Low Energy interface, which allows quick and easy configuration with a smartphone. Efento NB-IoT sensors can be integrated with any cloud platform.

You can use a free mobile application to configure the device and read the data from its memory.

  • Measurement range: 0 - 200 Centibar (kPa)
  • Temperature: -55 to +125°C, accuracy: up to 0.5°C in the range from -10°C to +85°C and up to 2°C in the range -55 to -125°C
  • Measurement period: 1 minute – 10 days (configurable by the user)
  • The device stores 40,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten
  • Batteries ensure up to 10 years of maintenance free operation
  • Use a free mobile application to configure the logger, read the data from its memory, generate reports and set alert thresholds

Newsletter (January)

NB-IoT CO2 sensor released!
We recently released the NB-IoT CO2 sensor. It may be used to monitor the CO2 levels (400 ppm – 5000 ppm) in office spaces to prevent spreading of COVID-19 disease.
NB-IoT motion / presence sensor released!
Allows to detect motion (like regular PIR sensor used in alarm systems) or room occupancy (conference rooms, office spaces, etc.). User can configure the device to detect every single movement or set the number of movements in a time period required to detect the room occupancy
Preserving stained glass windows for the next generations
Discover how Efento NB-IoT sensors are used by the conservation team of St. Marien church in Lübeck (Germany) to monitor the environmental conditions.
Efento CoAP loader update
Efento CoAP loader provides an easy and quick way to integrate Efento NB-IoT sensors into custom solutions. We recently updated it to support all sensor types and all their features
IoT connectivity from space?
Rakuten and University of Tokyo exploring low Earth orbit satellites for IoT coverage. The joint R&D project will span the next four years and involve the creation of a satellite network to connect NB-IoT and LTE devices.
