Important note:
This is a gas-phase NH3 sensor. It is not a direct NH3/NH4+ water-quality probe. In aquaculture projects it should be used as an auxiliary gas/ammonia risk indicator, not as a laboratory-grade ammonia concentration measurement in water.

Small breakout board with 2.54 mm header pins.
No standard IC footprint applies.
Type
Breakout board, sub assembly, plug in module
Thank you. These four parts are needed for an IoT water quality and aquaculture monitoring project using DFRobot Gravity/Fermion sensors with an ESP32-S3 and an ADS1115 ADC.
