FAQ:
Q: Which is the best soil sensor for Arduino?
A: The JXCT Soil NPK sensor is a low cost, quick responsive, high precision & portable Sensor that works with Modbus RS485. The advantage of this sensor over a traditional detection method is that it gives very fast measurement & data are highly accurate. All you need is to insert its probe in soil and get the reading using Arduino.
Q: What is the accuracy of the Arduino soil NPK sensor?
A: While talking about the accuracy of the sensor, it is up to within 2%. The nitrogen, phosphorous & potassium measuring resolution is up to 1mg/kg (mg/l). Using this Soil NPK Sensor, you can make your own Arduino Soil NPK Meter or any Cloud IoT Based Soil Nutrient Content Monitoring System.
Q: Is there a gas sensor for ammonia in water?
A: Googleing hasn’t found me anything but the MQ-137 which is a gas sensor for ammonia, not liquid. Think you fish will not like these test methods, but some google gave this lead – http://www.sensortips.com/zlevel/sensor-measures-dissolved-nitrate-in-water/ –
Q: What is the learn mode of an Arduino spectrometer?
A: The spectrometer has a “learn” mode and an “identify” mode. In the learn mode a known sample is placed in the unit and sampled at each wavelength of light emitted by the LED’s. The sampled values are stored in a database in the Arduino memory.
