Proximity TSL2671

This specific proximity sensor is configured via properties on the MBLProximityTSL2671 class. This section shows how to use its advanced features.

Configuration

The TSL2671 device has 4 configurable parameters that control the sensitivity and distance at which the detector can measure proximity. These parameters are set with properties on the interface.

Parameter	Description
Integration Time	How long the internal ADC converts analog input into digital counts
Pulse Count	Number of IR pulses emitted for distance measuring
Transmitter Current	Amount of current driving the IR transmitter

// set integration time to 5.44ms
// use default pulse count of 1,
// set drive current to 25mA
proximityTSL2671.integrationTime = 5.44
proximityTSL2671.proximityPulses = 1
proximityTSL2671.drive = .drive25mA

Proximity Data

Proximity data is an ADC value represented as an UInt16; the higher the adc value, the closer the distance to the object.

    print("Proximity ADC = \(result.value.uint16Value)")
