Envirotxt is a plug-in sensor that monitors power outages & temperature. Envirotxt uses a SIM card to send real time text message alerts over the GSM (mobile) network. Envirotxt is simple to install and very easy to use, just plug it in and send it a text message .. it's as easy as that! Envirotxt will send a text message alert straight to your mobile phone as soon as there is a power cut or when the temperature gets too low/too high.
All the temperature thresholds are user-programmable so you can decide what temperature triggers a text message alert and up to 5 users can receive alerts. Envirotxt is a completely wireless remote sensor, it only requires mains power and a SIM card to operate. Envirotxt has many features including a rapid temperature rise alert (see key features' on the left) and the text message control and responses are so simple it can be used by anyone (technical or not!). Note - Envirotxt uses capacitance' to store energy to send the power loss alerts, it has no dangerous lithium batteries inside.
Envirotxt has an internal temperature sensor and also a 1m external temperature sensor for monitoring more specific areas (both temperature sensors can send alerts).
