How to Use Our Thermal Monitors#

Our thermal monitors are built cheaply from electronic parts by volunteers and offered on that basis. You can keep the monitor for as long as you find it useful. If you don’t want it any more, or if it isn’t working, we’d be grateful if you would send it back to us so we can update the software and reuse it.

Do I need to read this?

For sites that have good wifi, we now ship the monitors with the wifi details already on them, so all they have to do is turn them on. For sites without, we either supply or advise them to buy a commercial data logger, usually a Thermopro 357s or a Lascar EasyLog device. You only need these instructions if you have one of our monitors and need to change the wifi network details or use it without wifi.

Before you start, you must decide which mode to use for your thermal monitor.

In internet mode

The monitor uses the wifi in the building to send readings to cloud storage. Choose this option if you have wifi that can be accessed by entering a network name (SSID) and password and if it covers the location where you are placing the monitor. This mode requires good wifi signal strength - if your wifi signal is poor or if you ever turn it off completely, choose “save” mode.

In save mode

The monitor saves the data for you to pick up every 3 weeks or so using a smartphone or laptop. Choose this option if your building doesn’t have wifi or if you are placing the device in a location where the wifi is poor.

What is Radio Mode?

Most monitors won’t work in radio mode. The ones that will are for venues that have wifi but need to monitor locations that are so hard to access it would be difficult to change the monitor batteries - like inside a church organ. They have an extra radio and a separate base station or “hub” that plugs into an electricity socket nearby. The monitor takes the temperature and relative humidity readings, sends them to the hub, and then the hub sends them to the internet.
