What are the data output forms of the laser ranging sensor?

2019-09-17
1, Digital output type
There are three main forms: RS232, RS485, and wireless transmission. The specific digital output type is selected according to the actual communication distance and terrain complexity.
(1) RS232 output, generally suitable for short-distance transmission within 10 meters, the ability to resist electromagnetic interference is weak;
(2) RS485 output, suitable for long-distance transmission, generally not more than 1000 meters, strong ability to resist electromagnetic interference;
(3) Wireless output, suitable for complex terrain
2, Analog output type
There are three main forms: analog current 4-20mA, analog voltage 0-5V or analog voltage 0-10V. The output current or voltage changes with the distance in real time, and the analog quantity corresponds to the distance value one by one. For example, the laser Distance Measuring Sensor SLDS-A30P measuring a distance range of 0.2-30 meters, the current output of 4mA corresponds to 0.2 meters (200mm) by default, and 20mA corresponds to 30 meters (30000mm). The corresponding relationship between the output current I and the distance L is: L = (I-4) / Δi + 200 (where Δi = (20-4) mA / (30000 - 200) mm) where the start and end points of the analog quantity, such as 4 mA Or the distance value corresponding to 20mA, can also be preset by the manufacturer according to user requirements (users can not change it by themselves), or the reserved interface is set by the user (use special setting software).
3, Switching output
This type of product can support multiple sets of relay switch outputs, corresponding to two preset distance values. When the measured distance reaches the preset value, the corresponding output is disconnected. Among them, the preset distance value can be preset by the manufacturer according to the user's request (the user can't change it by himself), or the reserved interface is set by the user (use special setting software).
The Laser Range Sensor of JRT is digital output type, welcome to buy.
