Problems solved by technology

[0003] Existing soil moisture sensors generally include wall-mounted humidity sensors used in laboratories and mobile humidity sensors. Most mobile and portable humidity sensors usually require more than two measurement personnel to perform correct measurement work, which costs extra It requires a lot of manpower and material resources, and it is difficult to ensure the safety of the humidity sensor, which greatly reduces the accuracy of the measurement. For this reason, we propose a humidity sensor

Abstract

The invention belongs to the technical field of sensors and particularly relates to a portable humidity sensor. The portable humidity sensor comprises a sensor main body and a detection head main body, the portable humidity sensor further comprises a safety protection movable support assembly, the safety protection movable support assembly comprises a bottom plate, side vertical plates and a fixedtop plate; supporting plates are further fixed on the inner sides of the two side vertical plates; mounting strips are respectively fixed at the left end and the right end of the sensor main body, and a bracket assembly is fixed on the opposite surfaces of the side vertical plates respectively; and the lower surface of the top plate is fixedly provided with a pressing assembly. According to the portable humidity sensor in the invention, an adjusting screw rod longitudinally and rotationally mounted on an inner supporting plate is arranged so as to adjust the longitudinal position of an adjusting supporting block, and then the kickback effect of the roller on the sensor main body is improved to the largest extent; a damping tube is communicated with two buffer air bags below the mounting strips, so that the buffering effect of the buffer air bags on the shaking process of the sensor main body is further increased, and the service life of the sensor main body is further prolonged.

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a portable humidity sensor. Background technique [0002] The humidity sensor is the simplest humidity sensor. There are two types of humidity sensitive elements: resistive and capacitive. The characteristic of the humidity sensitive resistor is that the substrate is covered with a film made of moisture-sensitive material. When the water vapor in the air is adsorbed on the moisture-sensitive film, the element Both the resistivity and resistance value of the sensor change, and humidity can be measured by using this characteristic. Humidity sensitive capacitors are generally made of polymer film capacitors. Commonly used polymer materials are polystyrene, polyimide, and acetic acid Fiber, etc., when the ambient humidity changes, the dielectric constant of the humidity-sensitive capacitor changes, so that the capacitance also changes, and the capacitance change is proportional to t...
