Data from distant and deep indoor places

CHESTER connects to the internet via LPWAN communication technologies (NB‑IoT, LTE‑M, and LoRaWAN are supported). Choose the built‑in internal antenna or connect an external antenna for any of those options. For diagnostics, parametrization, and device firmware upgrades, CHESTER comes with a Bluetooth Low Energy interface available in modern smart devices and notebooks.

Designed as a low power device

CHESTER has been designed from the ground up as a low‑power device and provides years of operation from the primary lithium cells. Another way to power the device is to use a rechargeable battery backup module with the optional solar photovoltaic panel input. For applications where batteries are not applicable, it is possible to energize the device from a standard 24 V DC line power or 230 V AC line.
