SEN0192 Analog? and Interrupts
Bart.Woodstrup 2024-12-17 04:56:56 1320 Views2 Replies I just started working with the Gravity Microwave sensor and I have a few questions. I am using SEN0192 with a DFRduino Nano v4.0
1) In the example code, you are using MCtimer2 and interrupts, but I am not sure why. What is the advantage (or need) for using interrupts?
2) Why isn't this sensor able to provide analog information?
Thank you, this is a very nice product.

The SEN0192 is a capacitive soil moisture sensor module. Here's how it relates to analog and interrupts:
Analog Connection:
The SEN0192 provides an analog output that corresponds to the moisture level in the soil. You connect the sensor's analog output pin to an analog input pin on your microcontroller (e.g., Arduino).The analog signal is a voltage that varies based on the moisture level, which can be read using the analogRead() function in Arduino or equivalent in other microcontrollers. The value typically ranges from 0 to 1023 (10-bit resolution), representing the dryness to wetness of the soil. Waqas.Tech 2024-12-17 23:52:15

Using MCtimer2 (or any timer with interrupts) can help you measure precise timing intervals when you're working with data that needs to be sampled at a specific rate or requires high accuracy.
