1. Application
HT20IoT monitor is designed for continuous measurement and conversion of
relative humidity and ambient temperature into a digital form (prot. Modbus TCP/IP ,
HTTP). The monitor programming is possible with the built-in web server. The monitor has
an LCD display field with 2x16 characters. The device allows you to send e-mail messages
informing about the current environmental parameters as well as events that cause
exceeding the alarm values. The monitor is powered via Ethernet - PoE (Power Over
Ethernet) or standard DC jack.
Features of HT20IoT monitor:
●
measurement, display and archiving of ambient temperature, relative humidity, dew
point and absolute humidity,
●
signaling of exceeding set alarm values
●
programming logic alarm outputs with reaction to the selected input value.
●
real-time clock function with clock supply support in case of the monitor power
failure
●
registration of input signals in programmed time
●
Ethernet 10/100 BASE-T
◦
protocol: Modbus TCP/IP, HTTP, FTP,
◦
services: web server, ftp server, DHCP client, SMTP client,
Values measured and calculated by the monitor:
Temperature,
relative humidity,
dew point,
absolute humidity,
wet bulb temperature,
saturated vapor pressure,
enthalpy.
All quantities and configuration parameters are available through the embedded Web
server, if the parameter is not visible, set it in the tab Settings-> registers on the website.
