MIKROE Tilt 3 Click is a compact add-on board used for measuring the tilt in multiple axes in relation to an absolute level plane. This board features the DSBA1P, a tilt sensor switch that breaks the circuit when tilted to an angle from ±30° to ±60° from NKK Switches. The DSBA1P is a non-contact switch with an embedded photo-interrupter that ensures high reliability, with a 1 million operation minimum. It is also very durable, sealed in the DSB construction for protection from environmental elements. This Click board™ is suitable for many applications where orientation or inclination detection is a crucial factor.

Tilt 3 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.

Tilt 3 Click as its foundation uses the DSBA1P, a PCB mount tilt switch sensor with ammonia-resistant terminals from NKK Switches. This switch is a non-contact switch with an embedded photo interrupter, which rather than contacts, ensures high reliability. It has sealed DSB construction for protection from environmental elements, including hydrogen sulfide, sulfur dioxide, and nitrogen hydroxide. These switch series are well suited to meet product safety concerns due to normally-closed (ON) status and can be used for many applications where orientation or inclination detection is crucial.

This tilt sensor works by detecting changes in angle from a pre-set “zero” state. They are set with a maximum and minimum threshold in which the application will work (from ±30° to ±60°) or be safe to operate based on the specific application’s needs. If the tilt or inclination exceeds these threshold values in either direction, a relay will be engaged, and the switch closed.

Tilt 3 Click communicates with MCU using two GPIO pins. The Enable pin, labeled as EN and routed to the CS pin of the mikroBUS™ socket, optimizes power consumption and is used for power ON/OFF purposes (driver operation permission). It also has an additional LED for exceeded angle threshold indication. In that case, such a condition is indicated by a red LED marked as TILT, which is also connected to the interrupt INT pin through which the user can receive the information, which, in addition to a LED, indicates unsafe or non-working conditions.

This Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
