Mynics-IR Module

Mynics-IR Module

The Mynics IR Sensor is a general purpose proximity sensor, which is usually used for obstacle detection. The sensing range is higher than most other modules. The module consists of an IR emitter and IR receiver pair and also an LM 358 comparator IC. The on-board LED indicator helps check the status of the sensor without using any additional hardware. The power consumption of this module is low and gives a digital/analog output.

Overview:

The sensitivity of the IR Sensor is tuned using the potentiometer. The potentiometer is tunable in both the directions. Initially, tune the potentiometer in the clockwise direction, such that the Indicator LED starts glowing. Once that is achieved, turn the potentiometer just enough in the anti-clockwise direction to turn off the Indicator LED. At this point the sensitivity of the receiver is maximum. Thus, its sensing distance is maximum at this point. If the sensing distance (i.e., Sensitivity) of the receiver is needed to be reduced, then one can tune the potentiometer in the anti-clockwise direction from this point.

Once tuned for a particular surrounding, they will work perfectly until the IR illumination conditions of that region are nearly constant.

For example, if the potentiometer is tuned inside room/building for maximum sensitivity and then taken out in open sunlight, it will require retuning, since the Sun’s rays also contain Infrared (IR) frequencies, thus acting as a IR source (transmitter). This will disturb the receiver’s sensing capacity. Hence it would need to be re-tuned, to work perfectly in the new surroundings.

The output of IR receiver goes low, when it receives a signal. The output pin is normally LOW because, though the IR LED is continuously transmitting, due to no obstacle, nothing is reflected back to the IR receiver. When an obstacle is encountered, the output of the IR receiver goes low. The IR signal is reflected from the obstacle surface. This drives the output of the comparator low. This output is connected to the cathode of the LED, which then turns ON.
