Abstract

The invention discloses a humidity sensor for agriculture. The humidity sensor comprises a control mechanism and a detection mechanism, wherein the control mechanism comprises a casing and a circuit board, the circuit board is mounted in the casing, an input end of the control mechanism is connected with an output end of the detection mechanism through a data cable, the output end is mounted on ahumidity sensor probe, and the humidity sensor probe comprises a probe body, a plug end and a mounting base. The humidity sensor probe acquires data of current humidity of a to-be-detected location and transmits the acquired data to a central processing unit through a data cable, data of the detection result are displayed through a display module after being corrected by the central processing unit, and the accuracy of the measurement result is improved. Meanwhile, the probe body and the plug end are plated with nickel under the condition that the measurement characteristics of the humidity sensor are not affected, rusting can be better prevented, the conduction performance is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of humidity sensors, in particular to an agricultural humidity sensor. Background technique [0002] With the continuous development of modern agriculture, the use of agricultural sensors is showing a trend of rapid growth, especially in the fields of agricultural Internet of Things, agricultural machinery and other fields with broad application prospects. The fast and accurate measurement of humidity by the humidity sensor can improve the scientific production basis for farmers and improve the comprehensive income of agriculture. Therefore, the humidity sensor is the most widely used sensor in modern agricultural planting. [0003] However, the sensitive structure and detection circuit of the existing humidity sensor will age during long-term use, resulting in a short service life. scientific production. Contents of the invention [0004] The purpose of the present invention is to provide an agricultura...
