M5 Stack Color Sensor RGB Unit (TCS3472) COLOR is a color recognition unit integrated with the TCS3472 chipset. As the name says, COLOR is able to detect color value and return RGB data as a response. Identify color principle: The TCS3472 chipset is integrated with a 3*4 array of filtered photodiodes and 16-bit analog-to-digital embedded converters. Out of the 12 photodiodes, 3 have red filters, 3 have green filters, 3 have blue filters and 3 have no filter (clear), which gives a total range of RGBA (RGB + Transparency) When detecting the color of an object the TCS3472 returns data from four channels: red(R), green(G), blue(B) and clear(C)(non-filtered). The response from the red, green, and blue channels (RGB) can be used to determine a particular source’s chromaticity coordinates (x, y). Applications: Product Color Verification Color tracking robot

M5Stack Watering Unit with Moisture Sensor and Pump Watering is a capacitive soil moisture detection and adjustment unit. The product integrates water pump and measuring plates for soil moisture detection and pump water control. It can be used for intelligent plant breeding scenarios and can easily achieve humidity detection and Irrigation control. The measurement electrode plate uses the capacitive design, which can effectively avoid the corrosion problem of the electrode plate in actual use compared with the resistive electrode plate. Applications: Plant cultivation Soil moisture detection Smart irrigation
