INTRODUCTION
In many cases, electrical isolation is required to ensure reliable operation of the sensors. Some sensors, such as pH sensors and conductivity sensors,they will interfere with each other and do not measure properly in the same container when they connect to the same power .To ensure stable and reliable operation of the sensors with no interference,it is necessary to isolate the signal and the power.
Gravity: Analog Signal Isolator is efficient in preventing the electrical interference between sensors. This module has an onboard 5V isolation power which could directly supply to the sensor. Therefore, you do not need to prepare the external power, such an easy and practical! The connector of wires are special designed for KDRobotKit 3Pin analog sensor, plug and play, no need for soldering. The analog signal transmission ratio is 1:1, which contributes to a very small impact on output signals of sensors when this module connect into the circuit. Futher more, you do not need to change the code of the mainboard.
This anlaog signal isolator is applicable to prevent interferences between sensors, such as multi-parameter water quality monitoring system that need to prevent interferences between water sensors.
Gravity: Analog Signal Isolator Interface
This product is almost compatible with all analog sensors produced by KDRobotKit. It could satisfy varied demands in situations which require electrical isolation.
- The MCU terminal (non-isolation terminal) should be provided with precise voltage of 5.0±0.1V. The higher the precision of input voltage, the higher the precision of analog output signal.
- This module consumes relatively large current during operation, so you'd better to provide external power supply to Arduino board to guarantee enough power and voltage precision.
- Please pay attention to the operating current of your sensor or module, the maximum output current from SEN terminal is 170mA.
- The GND of the MCU terminal(non-isolation terminal) and the GND of SEN terminal (isolation terminal) are isolated from each other. Do not short circuit them.
- It is normal for the isolator generates heat while working.
