Ammonia is also used in the agricultural sector as a direct nitrogen fertilizer, which is effective and economically viable.
What is ammonia and where is it found?
Ammonia is a colorless gas, slightly lighter than air. It is not an explosive gas in open spaces, but may be explosive in closed spaces. Ammonia is toxic at high concentrations and can cause irritation to the eyes, skin, throat and lungs, and at very high exposures - damage to the respiratory system or death. Therefore, its use and storage require appropriate safety measures. Monitoring ammonia concentrations in workplaces, the environment and industry is crucial to protecting human health and the environment. Ammonia poisoning manifests itself by muscle weakness, convulsions, hyperactivity and hearing impairment.
Suggested use of the sensor
- Detection of leaks in refrigeration installations on an industrial scale
- Underground detection of damage to ammonia pipes and valves
- Broadly understood environmental protection
- Smart farming
Special features of the sensor
- It has a modernized MEMS system for precise NH3 measurement.
- Compact dimensions (13 x 13 x 2.5 mm) allow for easy integration with other project components.
- It has low energy consumption.
- Provides precise and stable value reading.
- It has high sensitivity and short response time.
Precautions during use
- Before using the sensor, remove the protective film from it.
- Avoid using the sensor in an environment where it will be exposed to high concentrations of corrosive gases (such as H2S, SOX, Cl2, HCl, among others).
- Protect the sensor from contamination with alkalis, alkali metal salts and halogens.
- Avoid long-term exposure of the tile to unfavorable environmental conditions (such as high temperatures, high humidity, high pollution).
- Do not expose the module to water.
- Do not expose the module to vibrations, impacts or falls from height.
- Do not test the module on systems that involve personal security concerns.
