GSM Data Loggers

GSM Data Loggers

Wireless GSM humidity and temperature loggers use a built-in GSM modem to transmit data to a cloud server. The logger works according to the principle: woke up, measured, transmitted, fell asleep. In the absence of a mobile connection, the logger stores the received data of humidity and temperature in its own non-volatile flash memory.

For indication, a high-contrast OLED screen is used, which displays humidity and temperature values on all measurement channels. In addition, the signal level, battery charge and serial number are displayed on the screen. The logger comes with a rubber boot for shock and drop protection and has a built-in magnetic mount. The logger has two IP67 M8 connectors which one or two external Pt1000 thermotransducers or an SHT air humidity and temperature transducer can be connected to. The logger has a USB-C connector to connect a battery charger. The removable 18650 lithium battery of the logger can be quickly replaced as needed by the user.
