The TH868LRD and THUS915LRD are both Temperature and Humidity sensors with LCD for indoor air quality
applications from Ascoel.
The long rang radio transmission is based on the new disruptive LoRaTM long range technology in the following frequencies; the European EU868 and the American US915. These types of sensor have been designed in order to monitor Temperature and RH values in a room, meeting room or any generic indoor location.
The user can easily set between one or two thresholds for each physical characteristics from remote.
This impecable sensor can also display five rows of text messages, containing amid 21 characters each on the LCD screen. All the messages from the secure sever to the sensor have two additional bytes (one at the beginning and one at the ending of the message) so the user can specify the full length and checksum of the message.
As soon as the sensor receive the first TEXT message, if this is genuine, it will display the text and it replies to the sensor with an ACK message. Once received the ACK, the server sends the second message. On the same way, the sensor displays text and replies with an ACK and then the server sends the third message that will be showed on the screen. In case of multiple text messages, these will be displayed once at the time.
