Sorry, i'm not sure if this is the right avenue to ask for help... i have purchased a Catnip Soil Moisture Sensor v2.7.6, and i have it wired to a raspi pi I2C bus.... i got your code to work!!! but the moisture values seem to be way off... and once in a while the temperature reading is bad... also you can see that the address reads back as 255, but i did a SET to test and the address is absolutely 20!

i tried to put the sensor in some water, in my hand, on the table, and i can't get the moisture value to change at all.

any help??

I need help!
When a run the script I obtain the following error:

Traceback (most recent call last):
File "chirp.py", line 21, in
import smbus
ImportError: No module named smbus

I've installed python 2.7.18 and when I want to install smbus library using "sudo apt-get install python-smbus", I obtain the following error:

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package python-smbus is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'python-smbus' has no installation candidate

Thanks in advance for your help.

To fix it change:

    @sensor_address.setter
    def sensor_address(self, new_addr):
       
        if isinstance(new_addr, int) and (new_addr >= 3 and new_addr <= 119):
            self.bus.write_byte_data(self.address, 1, new_addr)
            self.bus.write_byte_data(self.address, 1, new_addr)  #<= ADD THIS LINE
            self.reset()
            self.address = new_addr
        else:
            raise ValueError('I2C address must be between 3-119 or 0x03-0x77.')

Will this work with Micropython on a Raspberry Pi Pico?

You could read version number as a wakeup call, this way it would be faster, saving the battery.
