Problems solved by technology
On the 380V / 220V low-voltage power line, it is difficult to be used for signal transmission due to too many electronic devices and too much network noise.
Although there are technologies such as power line remote meter reading, the effect is not ideal, so it has not been widely promoted

The invention relates to an ammonia gas sensor based on power line carrier communication, which consists of a sensor (1), a carrier measurement port module (2) and a direct-current stabilized power supply (3), and signals of the carrier communication sensor can be transmitted through a 220V low-voltage power line. The problem that signals are difficult to transmit due to the fact that too much electronic equipment is carried on a 220V low-voltage power line to generate high noise is solved, signal lines do not need to be rearranged, and engineering construction cost is reduced to a large extent on the premise that reliability is guaranteed. The ammonia gas sensor is applied to a smart agricultural monitoring system, and the measured object is ammonia gas concentration.
Description
technical field [0001] The present invention is an ammonia gas sensor which can transmit signals through 220V power line. The technical field relates to power line carrier communication and measuring instruments. Background technique [0002] The invention is mainly used for the measurement of ammonia gas in smart agricultural production, and can also be used in other fields. [0003] Smart agricultural monitoring will definitely involve the transmission method of the signal, which is related to the construction cost and reliability of the system. At present, the wired transmission method of arranging data lines and the wireless transmission method of Zigbee mode are used more. The wireless transmission in Zigbee mode is a kind of wireless communication similar to micro base station. The construction cost of this wireless communication method is lower than the wired communication of data line. However, stability and reliability are difficult to compare with wired communic...
