Product Description


Envirotxt is a new and innovative GSM (mobile network) device that monitors both temperature and power loss. It has a built-in temperature sensor which sends SMS alerts at pre-programmed user defined thresholds from -10 to +50°C. Envirotxt needs a SIM card to send SMS (text message) alerts through the mobile network. It needs a standard sized SIM card on any network except the Three Network as this is purely digital network.

Envirotxt has a quad-band GSM module so it can be used in almost all countries around the world. It can be used for a wide variety of applications including, second homes (e.g. fridge/freezers and frozen pipes), boats (e.g. shore power loss and preventing the engine from freezing), medical (e.g. critical fridge/freezers or keeping medicine at required temperatures, etc), warehousing (e.g. storage at correct temperatures and power loss), hydroponics, various utilities, server/comms room and much more.

Envirotxt is designed to have one master user who has full control of all its functions, plus up to 4 additional users. All temperature ranges can be customised by the user to alert at your required temperatures. E.g. you can set the temperature parameters at 3 – 20°C and Envirotxt will send an SMS alert if the temperature drops below 3°C and if the temperature rises above 20°C. It will also alert you when the temperatures goes back inside the pre-set range.

Envirotxt is simple and easy to use, simply plug in and send a couple of SMS messages, then you are in control and can set any temperature required for instant SMS alerts. Envirotxt has an internal temperature sensor and also an external temperature sensor so temperature can be monitored in a more specific location if required.

  1. Great product such a great idea 5 Star Review

    Easy set up and works really well. Just buy a PAYG card that can be topped up every 6 months and you’re up and running. Gives you piece of mind to know when power goes down

  2. Just the job 5 Star Review

    I was looking for something to protect our boats shore power connection - especially as last summer someone unplugged us which flattened the batteries and we lost chilled food.
    This neat unit sends text alerts so I can call the marina to pop along to the boat and make sure power is connected again. Much better than some people trying to use an old mobile phone with an app.

  3. Brilliant for the price 5 Star Review

    Great product at a great price.
    Arrived when promised.
    Make sure you get a PAYG that has 6 months without calls needing to be made to keep the SIM active. EE claim that just a single SMS message will keep the SIM active every 6 months or earlier. Other network operators need voice calls made which means putting the SIM in an old phone at periodic intervals.
