AUTONOMOUS INTRUSIVE ALARM WITH GSM SYSTEM

Today any instrusive detection, its likely agree. But normaly need external power, or required wifi or bluetooth link. Have multiples inconveniences aboutthis because all this systems are posible broken by power off or another hacks systems.

The systems are i show no need power or external signals, only need sun!

Step 1: WIRING

The solar panel charge the battery by charger module and power with 3,7v the SIM900L module. The arduino and PIR module power with 5v by boost module. Important this module previous regulated, your connect 3.7v power supply and resulted with screw your OUT to 5v.

The cosumition over 100mA except when SIM900L call up 2A. I test in south of Spain and battery never down 3.2v, its minimal voltage to SIM900L.

I recomendad in another sites with less sun increase the battery from 200mA to 3600mA.

I recomendad sim without PIN, can you deactivate from some phone.

Step 2: CASE

The case are design to minimal space and support over any wall. This case support panel and all electronics, its discrete an can you attach with magnetic to any support.

Can you get the design above.
