The configurable NB-IoT/LTE-M/LoRaWAN environmental sensor that samples, aggregates, and reports temperature and humidity.

The CHESTER Clime catalog application allows for setting optional temperature low/high alerting. Also, it comes with several firmware variants offering 1-Wire thermometer (DS18B20), or connection to a Soil Sensor from HARDWARIO (measuring soil mosture and temperature), or RTD thermometers such as Pt 100 / Pt 1000.

Battery-friendly wireless connectivity

The device transfers data over cellular networks (NB-IoT / LTE-M) or public/private LoRaWAN networks.

Digital temperature and humidity sensor

Thanks to the protective PTFE membrane, the accurate sensor is dustproof and splashproof (IP65).

5 years battery lifespan in extreme outdoor

The device can operate in harsh environmental conditions on a single primary lithium cell for a long time.

Fast deployment and seamless integration

Use the HARDWARIO Manager iOS/Android app to set the device and integrate its data from HARDWARIO Cloud.

Application areas

Typical use cases

The multi-functionality of CHESTER Clime allows a precise control of the environmental conditions in cowsheds.

Moreover, it helps to create ideal living and working conditions by monitoring indoor air quality with respect to temperature, humidity and more.

To avoid outages caused by equipment deterioration, CHESTER Clime can track and report the environmental conditions of switchboards.

Among other applications, it is also instrumental in reducing waste of both food and medicine by tracking and managing refrigerator temperatures.
