These solar powered rotating animal warning signs use the 4G SMS Lite for remote control.
When stock is being moved, or there is a report of stray animals in the location, a text message is sent to the SMS Lite.
The text message to control the sign is simply “ON Sign”.
When the warning sign receives the text message, the SMS Lite operates it’s relay outputs. The sign then starts to rotate and the amber warning lights start flashing. The photos show the warning sign rotating at its installed location in regional NSW.
A key requirement for our customer was to notify five people that the sign has been activated. The notification message they will all receive is “Sign has switched ON”.
The SMS Lite easily achieves this requirement as up to eight mobile numbers can be added to it’s address book.
As the warning signs are solar powered, the power consumption of the SMS Lite was also an important project consideration. With a current draw as low as 13mA, the system designer was able to easily integrate our controller within the system power budget.
The SMS Lite is easy to set up – simply by sending it a few text messages. The SMS Lite also has some powerful features like pulse outputs, supply voltage monitoring and input debounce options.

Relay Contacts – The output relay contacts in the SMS Lite are low power DC contacts. They will need interface relays or contactors to operate high current and AC mains powered pumps.
