Today, the editor will share with you the relevant knowledge points about how to achieve automatic watering in MicroPython. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

Experimental purpose:

Learn the method of extending the simple Icano interface in the PC system

Learn TurnipBit splicing programming

Learn the working principle and application method of soil sensor

Required original devices:

TurnipBit development board

TurnipBit expansion board

One usb cable

Soil moisture detection module

Some DuPont lines

The principle of soil moisture detection module:

The soil moisture detection module is mainly used to measure the soil volume water content. Based on the principle of electromagnetic pulse, the apparent dielectric constant (ε) of soil is measured according to the propagation frequency of electromagnetic wave in the medium, and the soil volumetric water content (θ v) is obtained. when the soil moisture reaches a certain standard, it begins to water.

Connection method:

The TurnipBit expansion board corresponds to the LED interface as follows:

Source code:

Open the TurnipBit visual programming address www.turnipBit.com

The code is as follows:

From microbit import * while True: if pin5.read_digital (): pin8.write_digital (0) display.show (Image) else: pin8.write_digital (1) display.show (Image.HAPPY)
