Description:

This is a set of transmitter and receiver in one of the photoelectric sensors. 1 detection distance can be adjusted according to the requirements. The sensor has a detection distance, by small visible light interference, cheap, easy to assemble, easy to use features, can be widely used in robot obstacle avoidance, line piecework and many other occasions.

Application:

1. the production line goods automatic counting device

2. multi-reminder

3. maze robot

Photoelectric switch E18 technical parameters:

Sensors answer frequently asked questions about:

Q: This is a digital sensor or analog sensor

A: This NPN type photoelectric switch. Output Group Aung station is 0,1, ie digital circuit high and low

Q: What is the level of output is detected the target object?

A: The goal is to detect low-level output, the normal state is high output

Q: Can IO port connected to the microcontroller?

A: The output of an external pull-up resistor can be connected to the IO port

 Q: How much pull-up resistor?

A: pull-up resistor is generally about 1K

Q: Where can I download the instructions? Or too simple instructions

A: This is a photoelectric switch, three lines, power, ground and output, not too complicated introduce digital output, no AD conversion can be directly connected to the microcontroller through the back IO ports adjust potentiometer adjustable distance (3 -80CM effective)
