Some sensors' micropython lib, including BH1750, JW01 and a Capacitive Soil Moisture Sensor.Demo is included.Code are tested on a esp32 board.Written by myself.
一些自己写的传感器的micropython库,包含BH1750,JW01和一个电容式土壤湿度传感器,并含有示例程序.本文中的图片仅作示例,无购买引导倾向,若有侵权请联系我删除!谢谢🙏代码在esp32板上测试可行.

BH1750 light sensor

First, copy BH1750.py to the root folder of your device. 首先把BH1750.py拷贝到单片机的根目录下.
Then connect the BH1750 to the gpios. 然后连接BH1750到指定引脚.

import BH1750
from machine import SoftI2C

s = BH1750.BH1750(SoftI2C(Pin(19),Pin(23))) #Initialize BH1750 sensor with SoftI2C(Pin(19),Pin(23)) 初始化传感器,在SoftI2C(Pin(19),Pin(23))上
print(s.luminance(0x20)) #Measure in ONCE_HIRES_1 mode once and print result on terminal 在高精度模式1下测量一次并且打印到终端 

This demo initializes a BH1750 instance, and measured once and printed the result to terminal. 这个示例初始化了一个BH1750实例,并且使用其读取了一次然后打印.
Other methods and mode are listed here 其他的全部方法和模式如下:

#modes 所有可选的模式
PWR_OFF = 0x00
PWR_ON = 0x01
RESET = 0x07
CONT_LOWRES = 0x13
CONT_HIRES_1 = 0x10
CONT_HIRES_2 = 0x11
ONCE_HIRES_1 = 0x20
ONCE_HIRES_2 = 0x21
ONCE_LOWRES = 0x23

#methods 方法
#assuming s an instance of BH1750 class 假设s是BH1750类的一个实例
s.on() #Turn on the sensor 打开传感器
s.off() #Turn off the sensor 关闭传感器
s.reset() #Reset the sensor 重置传感器
s.set_mode(mode) #Set mode 设置模式
s.luminance(mode) #Read with mode and return result 以指定模式读取并且返回结果

JW01 CO2 sensor

First, copy JW01.by to the root folder of your device. 首先把JW01.py拷贝到单片机的根目录下.
Then connect the JW01 to the gpios. 然后连接JW01到指定引脚.
JW01 works on 5v electric level while most devices work on 3.3v, so make sure you have done the conversion. JW01工作在5v电平而大部分单片机是3.3v电平,所以请确保做好了电平转换.

from machine import UART
from JW01 import JW01

uart1 = UART(1,baudrate=JW01.BAUDRATE,bits=JW01.BITS,parity=JW01.PARITY,stop=JW01.STOP,tx=17,rx=16)
jw01_sensor = JW01(uart1) #Initialize JW01 sensor on gpio 16 and 17, using UART resource 1 在gpio16和17上初始化JW01,使用UART1资源

print(jw01_sensor.measure()) #Read and print 读取并显示
