A soil moisture detection device based on single chip microcomputer

Abstract

The invention discloses a soil humidity detection device based on a single-chip microcomputer, which has a long battery life, low energy consumption and no wiring; it includes: a humidity sensor for detecting soil humidity, which detects its humidity by inserting a probe into the soil; a LORA module , for wireless communication with external devices; single-chip microcomputer; memory, for storing data; battery, for powering electrical equipment; photovoltaic film, for generating electricity through solar energy, and storing the emitted electricity in the battery; The signal end of the single-chip microcomputer is respectively connected to the output end of the humidity sensor, the signal end of the LORA module, the signal end of the memory, and the signal end of the battery management system, and the input end of the humidity sensor is electrically connected to the output end of the probe. The invention has a simple structure and can realize signal communication and acquisition under the premise of low power consumption. In addition, the use of photovoltaic thin film power generation to increase the battery life can completely avoid the problem of wiring, and at the same time solve the problem of battery life.

Description

technical field [0001] The invention relates to soil moisture detection technology, in particular to a soil moisture detection device based on a single chip microcomputer. Background technique [0002] In the process of planting research or planting in greenhouses, the detection of soil moisture is very necessary, and because the general planting area is too large, several soil moisture detection devices are required to be distributed around the planting clods. So as to achieve a relatively comprehensive detection. However, there is a problem in how to collect the signals of each humidity detection device and supply power to them. First of all, it is obviously unreasonable to lay a large number of communication and power supply lines, which is not desirable; secondly, although the above problems can be solved by using battery power supply and wireless signal transmission, how to increase the battery life and how to achieve low-power signal transmission is still a problem. ...
