Gravity: NH3 Sensor (Calibrated) - I2C & UART Shipping:1 day This allows additional IO to

This allows additional IO to be connected to the board and the state of these can then be read or controlled by the Pico

The module also features 16MB of flash memory

Utilizes the extremely common HD44780 parallel interface chipset ([datasheet](http://www

so this kit can be used as an alternative to the AXE033

ENS160 is an air quality sensor based on ScioSense's new ENS160 sensor chip

Gravity: NH3 Sensor (Calibrated) - I2C & UART Shipping:1 day This allows additional IO toThis is a sensor that detects ammonia concentration and supports three output modes: analog, I2C, and UART. The probe has been calibrated at the factory, which can quickly and accurately measure the concentration of ammonia in the environment. Can be widely used in the detection of ammonia in industrial and environmental protection fields. The probe adopts the electrochemical principle, has the characteristics of strong anti interference ability, high
