The PIR (Passive Infra-Red) Sensor HC-SR501 is a pyroelectric device that detects motion by measuring changes in the infrared levels emitted by surrounding objects. This motion can be detected by checking for a high signal on a single I/O pin.
Module provides an optimized circuit that will detect motion up to 6 metres away and can be used in burglar alarms and access control systems.
The PIR sensor and Fresnel lens are fitted onto the the PCB. This enables the board to be mounted inside a case with the detecting lens protruding outwards, whilst still allowing easy access to the controls inside the case.

This is a GSM & GPS Modem based on Simcom's SIM808 Module. This GSM-GPS Modem is perfect for projects which require both GSM Modem & GPS Module. SIM808 module is a GSM and GPS two-in-one function module. It is based on the latest GSM/GPS module SIM808 from SIMCOM, supports GSM/GPRS Quad-Band network and combines GPS technology for satellite navigation.
It features ultra-low power consumption in sleep mode and integrated with charging circuit for Li-Ion batteries, that make it get a super long standby time and convenient for projects that use rechargeable Li-Ion battery. It has high GPS receive sensitivity with 22 tracking and 66 acquisition receiver channels. Besides, it also supports A-GPS that available for indoor localization. The module is controlled by AT command via UART.
