Based on OneNET's remote temperature and humidity monitoring system training report

Secondly, the paper gives the overall design of the system, and according to the design requirements, with MSP430F5438 microprocessor, radio frequency module CC25 radio frequency amplification front-end CC2591 and SHT10 temperature and humidity sensor And the environmental perception sensor is the core, and the sensor hardware node is built.

PLC-based temperature and humidity control system. The current situation of research at home and abroad. You can go to Wanfang or Zhiwang to download some master's thesis. Generally, master's thesis has chapters of domestic and foreign research. You can use it directly or summarize a few articles. If there is a download problem, I can help you download it. .

When verifying, the cold storage time generally does not exceed one hour during the door opening operation or power cut-off insulation.

Temperature and humidity monitoring system: The temperature and humidity monitoring system can monitor the temperature and humidity of enterprises, provide real-time temperature and humidity data and analysis reports, and help enterprises control the indoor environment and improve indoor comfort and work efficiency.

Integrated with the underlying data acquisition system, it can view dynamic ring data such as temperature and humidity and water leakage monitoring in real time, and can update the real-time data of power distribution monitoring. The 2D panel displays ledger information and power distribution monitoring.

I) Enterprises should configure an automatic temperature and humidity monitoring system to carry out 24-hour continuous and automatic monitoring and real-time recording of the temperature and humidity of the warehouse through automatic monitoring and data acquisition of the temperature and humidity of the warehouse environment.

How much is the wireless temperature and humidity recording acquisition and monitoring system?

Therefore, the cost is difficult to estimate, ranging from more than 100,000 to millions.

The temperature and humidity recorder used in pharmacies: portable temperature and humidity, the cheapest one is fine.

The price of the computer room power environment monitoring system varies depending on the brand, model, function, region and other factors, so it is difficult to give an exact price range. Generally speaking, the power environment monitoring of the computer roomThe price of the system ranges from thousands to hundreds of thousands, and the specific price needs to be selected according to the actual demand and budget.

temperature and humidity detection system requirements

Hardware equipment: temperature and humidity sensors, blowers, accelerators, computers, etc.

The instructions for using the electronic thermometer are as follows: push open the battery door in the direction indicated on the back of the machine, take out the battery gasket, and then replace the battery door, and the machine can be used.

The product adopts a digital temperature and humidity sensor, which displays the temperature and humidity values in a digital tube, with fans and heater contacts, and has load disconnection alarm, sensor fault indication, RS485 communication and other functions. It is suitable for the requirements of unattended substations.

Temperature control: Ensure that the constant temperature system can provide stable temperature control.Choose suitable temperature control equipment, such as constant temperature water bath, thermostat or air conditioning system, to accurately control the temperature according to the experimental requirements. Pay attention to factors such as temperature range, stability and uniformity when selecting equipment.

STM32-based temperature and humidity monitoring system design

Measure and display temperature and humidity main functionCall the DHT11 reading data function and call the lcd display function to display the temperature and humidity.

[Abstract] This paper adopts STM32 single-chip microcomputer as the core processor, uses the internal RTC perpetual calendar to provide time and date for the system, and uses a solid-state relay for level level conversion. The control time is provided by the timer counter inside the single-chip microcomputer, and the digital temperature sensor DS 18B20 reads the external temperature data and transmits it to the inside of the computer.

Therefore, we need a low-cost, easy-to-use and accurate temperature and humidity meter.

The significance of the design of stm32 home environment inspection system is that it allows users to monitor the indoor environment in real time at the detection site, and also allows users to monitor the living environment and safe environment of the house in real time through remote transmission technology.The design of the stm32 home environmental inspection system adopts an embedded development platform equipped with sensors to monitor data.
