Mikroe MIKROE-2985 Hall Switch Click is a magnetic-field activated dual-relay Click Board. Mikroe MIKROE-2985 Hall Switch Click has two high-quality compact relays which allow switching of high voltages of up to 220V. These relays are activated by the Hall-effect sensor. When the north pole magnetic field is introduced to the sensor, one of the relays will be activated. When the south pole magnetic field is introduced to the sensor, the other relay will be activated.
