- Working voltage: 3.8V-5.5V
- Operating current (5V): typical current 6mA
- Input / output signal (3 lines): GND OUT VCC
- VCC, GND is the power supply, the VCC range is 3.8V-5.5V
Multi circle precision adjustable potentiometer on the board, can be adjusted according to the use of the environment. Adjust range from 3cm-100cm. because it is the reflection principle, with the specific reflection of the target, can be adjusted according to the situation.
Digital signal output, the sensor contains the necessary modulation and demodulation, logic processing.
Working principle: the sensor active infrared emission, according to the reflected light detection, if detected obstacles, OUT foot output 0, otherwise 1
There is a red LED on the circuit board, and the.OUT output continues to be low when the obstacle is detected. The barrier is the high level of the OUT output.
Obstacle detection time (the obstacles to effective target detection range from obstacles or obstacles to the obstacle disappeared): <=21ms
Sensor active infrared reflection detection, so the reflectivity and shape of the target is the key to detect the distance, which is the smallest black detection distance, white maximum; small area object distance is small, large area distance.
The following is the actual test of the detection distance:
Detection distance (test environment, indoor, maximum power, Voltage 5V, power consumption 6.5ma):
1. ultra micro, and the design of mechanical mounting holes.2. less power consumption, wide operating voltage range. The transmit signal is modulated by the modulation signal, the distance is far, the anti-interference is good, can work under the outdoor non direct sunlight (the distance will be shorter).3. range adjustable, ranging from 3cm-100cm.4.to avoid the use of window technology to avoid the critical area of the problem, the sensor work is very stable, users directly use the output signal, do not need to consider the issue of signal jitter.5. the price is cheap, but the performance has exceeded the market in the infrared obstacle avoidance sensor.
1. white walls: 100cm
2. IBM black computer cover: 20cm
3.1 fingers: 18cm
4. Palms: 30cm
5. a transparent original bead pen: 20cm
A transparent original bead pen can sensitively detect.
The new version has done a very big improvement, has become more and more perfect, the characteristics are as follows:
