GSM SMS alert system
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."
