ZE03-NH3 Gas sensor can be used to measure Ammonia gas concentration in atmosphere.
This is an Industrial grade sensor and is are very easy to interface to your Micro-controller,
Arduino as well as Raspberry Pi as they have linear Analog output as well as UART output (3 volts).
ZE03 Series of Gas Sensor Modules by Winsen is a general-purpose and high-performance
electrochemical module. It uses three electrodes, electro-chemical gas sensor and high-performance
micro-processor. By using this GAS Sensor you will be able to Monitor concentration of Ammonia gas.
It is with built-in temperature sensor to make temperature compensation, which makes more accurate
to detect Ammonia gas concentration. It has the digital output as well as analog voltage output at the
same time which facilities the usage and calibration and shortens the development period. It is a
combination of mature electrochemical detection principle and sophisticated circuit design,
to meet customers different detection needs.

(1) High Sensitivity, device responds very quickly to the testing environment, no cover means the sensor
will have maximum contact with the air; a cover sometimes will increase the temperature
inside the device and will affect the sensor reading.
(2) High Accuracy, sensor value calibrated by the factory and figure displayed in four digits, can tell
any difference in 0.001 units. After comparison with other expensive and large size industrial
readers, the data this unit gets show low deviation from other professional readers!
(3) After hundreds of testing by our engineers, we have used the best and most suitable sensor to ensure the
accuracy and stability. We can also install other sensor brand upon your request, or add other
functions, like Remote Reading, automatic Data Log etc., please contact us with your requirement.
We offer Custom Design and Manufacture service with no minimum order required.
(4) Portability and easy to use, Plug and Play, you can now read your figure anytime anywhere with a
USB power adaptor. We do not install the cover, display directly the inside design and sensor, to offer
the most Cost Effective Solution to our customers.
(5) Factory Direct Sale, Manufacturer to Consumer Directly! Guaranteed Best Price on Internet!
(6) Free Shipping Worldwide! Production will take 5 days. Delivery normally will take around
7 – 12 days. Tracking number will be provided! We also offer Express Shipping (upon request
with extra cost) which will take 3 – 4 days if you wish to speed up.
(7) FULL REFUND for item Not Working or Lost in Mail! No Questions Asked Policy. Please buy with
Confidence. Positive Feedback Left Automatically after order being placed!
