ETH1: Compute Module 4 Built-In

Take your next outdoor sensor project to the next level with this SHT-30 based temperature/humidity sensor

so all you have to do is solder on straight or stacking headers and the terminal blocks

Many coders are unfamiliar with the underlying technologies that make their programs run

CircuitPython and Arduino library code

Gravity: Analog TDS Sensor/Meter for Arduino _Maker ETH1: Compute Module 4 Built-InThis is an Arduino compatible TDS Meter Kit for measuring TDS value of the water, to reflect the cleanliness of the water. It can be applied to domestic water, hydroponic and other fields of water quality testing. TDS (Total Dissolved Solids) indicates that how many milligrams of soluble solids dissolved in one litre of water. In general, the higher the TDS value, the more soluble solids dissolved in water, and the less clean the water is. Therefore,
