Details in the documentation.


Description

The sensor is based on Vishay's TSSP77038 chip - an infrared receiver operating at 38 kHz. The sensor in combination with the IR LED controlled by the popular NE555 timer forms a complete distance sensor module with digital output. The circuit requires voltage from the range for proper operation: 3.3 V to 5 V. The module is available in a version that detects objects within a range of up to 30 cm or 60 cm, so it can serve as a sensor to detect obstacles in the minisumo competition. The performance of the sensor depends on many external factors such as the size and shape of the object, the type of surface to be measured, etc.

Connection method

The module has four outputs: ground potential (GND), power supply (VDD), digital output (OUT) and pin responsible for switching on the transmitting diode (ENABLE).

The power supply for the sensor given on the VDD pin should be in the range from 3.3 V to 5 V. Voltage below 5V decreases the power of the transmitting diode, which also decreases the sensor range. To use the module in full range with 3.3V power supply, make a jumper between the pads left on the emitter side (picture next to it).

The sensor output (OUT) is a digital signal pulled to the power supply voltage by default (high state - logical one). While the sensor detects an object, the output state will change to low (logical zero), this fact will also be indicated by a red LED.

The ENABLE output is used to control the IR transmitting diode. If it is not necessary to switch off the transmitter, you can leave the pin unplugged because by default it is pulled to the power supply voltage, which makes the diode switch on. The status of the transmitter is indicated by the green LED - it lights up when the transmitter is switched on.

All four outputs have a standard spacing of the popular goldpin strip - 2.54mm (0.1"). This makes it easy to connect the module to the contact board or to the circuit using wires.

Changing sensor parameters

A potentiometer mounted on the receiver side is used to adjust the frequency of the IR transmitter. The measuring range can be optimised by adjusting the potentiometer accordingly. The easiest way to set this parameter is to observe the behavior of the sensor output when turning the potentiometer knob.

Limitations

  • The sensor has a digital output. This means that it will give information whether the object is within the measuring range without the exact distance in which it is located.
  • The sensor's operation depends on the type of surface to be detected and the shape of the object.
  • The sensor can be triggered by strong ambient light (e.g. very bright lights).
  • Several sensors used at the same time can interfere with each other.

On the left, the sensor output oscillogram interferes with strong light from the lamps (bottommost light). On the right, the output oscillogram while an object is at the threshold of detection.

Diagram

The module contains the necessary passive components for proper sensor operation.
