Hygrometer for temperature, relative humidity, CO2, TVOC and light intensity / 4GB memory / Power over Ethernet / MQTT / Email alarm / HTTP / FTP
The hygrometer is used to measure and store environmental data such as temperature, humidity, illuminance, CO2 content and TVOC concentration. The hygrometer also calculates the dew point, absolute humidity and the water vapor content in the air. The hygrometer is used for stationary monitoring of laboratories, greenhouses, medicine and food stores, museums, etc. The data measured and calculated by the hygrometer are stored in the internal memory and can be called up via Ethernet and sent to the user. In addition to storing the measurement data, the hygrometer can send alarms by email or display them on a website. The hygrometer can be supplied via a power supply unit or autonomously via Power over Ethernet. An internal battery is built into the hygrometer to buffer the memory and the settings.
In addition to the built-in Ethernet interface, the hygrometer also has an RS485 interface available to the user. This can be addressed via Modbus RTU. The user can communicate with the hygrometer via Modbus TCP / IP, HTTP, FTP via the Ethernet interface. A web and FTP server as well as a DHCP and SMTP client complete the functionality of the hygrometer's network interface.
