Product Code: TM-CELL540-S

The Solar Cellular Edition, a weatherproof, environmentally-hardened, solar-powered temperature monitoring device ideal for remote locations and outdoor operations. The Solar Cellular Edition continues reporting temperature readings via its Sensor Cloud technology, regardless of available electrical sources. Additionally, it offers extended-life battery power, plus the latest software to ensure the device operates effectively and efficiently while remaining up to date. Like the original, this version of the product also transmits data over mobile data networks, meaning that it is not reliant upon a traditional Internet connection to continue monitoring and reporting temperature changes. Over-the-air updates are also available, allowing for remote software upgrades no matter where sensors are located.

The temperature sensor is accurate to within ±0.5°C and can report temperatures from -40°F to +200°F. There are optional industrial sensors: soil moisture, wind speed, tank level, tipping bucket, and more in development. Temperature@lert Solar Cellular Edition just magically turns on once it is placed in sunlight.

How it Works:
Using GSM cellular phone networks, Temperature@lert Outdoor Cellular Edition provides 24/7 monitoring to provide out of range temperature alerts to you via emails, text messages, and/or a telephone call. It will also alert you when the temperature returns to normal. Rechargeable batteries provide power when it’s dark or overcast for up to four weeks. Our fault- tolerant design means if our system ever fails to hear from your device, we'll alert you right away that something's not quite right. Plug-and-Play Smart Sensor options include Temperature, Humidity, Soil Moisture, Tipping Bucket, and Wind Speed. An optional contact closure output can replace one of the sensors.

Flat rate monthly monitoring plans include everything needed for operation (cellular service, alerts, backups, security, and online hosting at our SAS70 level 2 datacenter): monitoring plans for cellular editions Contact us if you wish to pay annually.

You Are Protected:
If the battery ever runs low, the Temperature@lert Solar Cellular Edition can alert you to a low battery. No need to worry about telephone lines being downed from a storm - Temperature@lert Solar Cellular Edition transmits wirelessly over the GSM mobile phone networks. If our system ever fails to hear from your device, the HealthCheck feature will alert you right away that something's not quite right.
