Distributed wireless low-power temperature and humidity monitoring system for vegetable base based on MSP430luanchpad.

This project uses msp430g2231 as the core processing chip, which is composed of sensor acquisition module, wireless communication module, alarm module and host computer; two msp430 launchpads are used to simultaneously collect temperature and humidity through the dht11 temperature and humidity sensor, one as the host and the other as The slave machine uses a wireless communication module to communicate with the host machine, and the communication distance is more than 20 meters; the host machine directly communicates with the computer to transmit the temperature and humidity data to the computer, and at the same time, the upper limit of temperature and humidity can be set for The computer alarm can be used to differentiate between the host and the slave by playing specific songs or recording. In this way, you can first hear the changes in temperature and humidity. If you want to know the specific values ​​of temperature and humidity, you can directly check it through the host computer. Specific temperature and humidity values ​​enable real-time monitoring of the temperature and humidity of greenhouse vegetables, greatly improving the efficiency of large-scale planting.

High-precision digital display counter

In industrial control, it is often necessary to count and measure products to achieve automatic control of equipment. This article introduces a method of making a counter that can set the count value arbitrarily within the display range. Moreover, the current count value, set value, and magnification value will not be lost when power is turned off. It is compatible with a variety of input signals and has a magnification accuracy of up to 5 digits. It is easy to use, stable and reliable, and can be widely used in machine tools, rubber, printing, pharmaceuticals, and cables. , textile, complete sets of control equipment and other industries.
