1Introduction
The reed relay is a switch which is operates with the presence of magnetic field. The sensor module can be
used to detect the presence of magnetic field and can be used for various applications such as a magnetic lock
and anti theft alarm etc.
2Features
Adopts high quality reed switch
Power supply indicator lamp
Comparator output indicator lamp
AO reed switch output
DO comparator output
3Specifications
Power supply: 3V –15V
Size: 36 mm x 16 mm
Comparator output current: 16 mA
4Hardware Connections
The module has 4 pin header mounted on the board. The pins are A0 which is for reed relay output and D0 is
for comparator output. Figure 1 below shows the pin layout for the reed relay.

5Pseudo Code
boolean getReedRelayStatus(void)
{
// read D0 pin status
if(gpioReadPin(D0) == 1)
return true; // reed relay on
else
return false; // reed relay off
}
