I came across the MiFlora soil measuring device from Xiaomi.
I saw that it claims to measure the pH levels of the soil together with moisture levels, temperature, and light. However, I was surprised to see that a pH sensor is usually double the price of the MiFlora.
Therefore, I was curious to know how MiFlora can determine the pH of the soil, but I could not find anything about it.
Do you guys know if what Xiaomi is claiming to sell is a bit of a scam or is there a way they can actually measure the pH with such a device?
