Tempmonitor

A custom made monitoring distribuited system to get temperatures from a lot of DS18B20 devices embedded into multiple refrigerators using an existant network of 4-wire cables.

4 slave devices grab the temperatures and send them to a master who work as gateway to the monitoring server. The data is sent using MQTT to a node-red istance who make store them in a mysql database. The node-red also is used to do some analisysand generate alerts.

A php basd web dashboard is then used to display the system status.
