Low cost GSM SMS alert system The new GSMBlackBox is a compact SMS text alert module which can send a fixed text message to two recipients when either or both of its two volt-free digital inputs are triggered. Powered by 9-15v the GSMBlackBox is ideal for remote application when you need to be informed if there is a fault or a problem. Configuration is simple just add the two recipients phone numbers to the SIM card and insert in the unit - next time the inputs are triggered the text message is sent. Remote control the transistor output by calling the unit. "A low cost add-on to any control or alarm system to keep you informed by text message wherever you are."
