Temperature and humidity need to be controlled in many modern industry fields. The control method of temperature and humidity is mainly through the monitoring of a sealed or semi-sealed space, and measures of increasing and decreasing temperature and humidity. So how to control the temperature and humidity is bound to be applied to the relevant temperature and humidity monitor for monitoring.

Based on the depth information and energy of nodes, an efficient multicast routing algorithm based on tree structure is proposed. Specifically, a concentrator (base station) is a root node, and a collector (sensor) is a leaf node or a tree node. The network routing includes three processes. (1) The tree initialization process. The base station discovers child nodes by broadcasting sub-request packets to complete the initialization of tree generation. (2) New node join process. The newly deployed sensor node looks for its parent node by broadcasting the parent request packet, so that its neighbor node knows its existence. (3) The node leaves the process, when the node's battery is depleted over time, or when the node is destroyed by a bad environment and becomes a useless node, the node will disconnect communication with other nodes.

Temperature and humidity monitor based on the Internet of things technology, three-dimensional table temperature, humidity monitoring system transmission distance can reach 100 meters. The collector's transmit power consumption is 1mW, and the sleep mode consumes less power. Two sections of the 5th battery can maintain up to 1.5 years, the resolution of the temperature measurement is 0.1 °C, the humidity is 1% RH uncertainty is U = 0.3% RH (k = 2), the acquisition system is successful in one-time data collection The rate is above 99.8%, which can be widely used in the company's various types of warehouses and laboratory environmental monitoring. The system realizes automatic monitoring of temperature and humidity at multiple monitoring points, automatic recording, automatic saving, automatic alarming, and multiple forms of inquiry. It adjusts windows, air conditioners, dehumidifiers and other equipment in the table according to the feedback information. It can meet the requirements of the new standards for electric energy meters issued by the State Grid Corporation of China.

TPU Color Change Film

TPU Color Change Film have TPU Carbon Fiber Film, TPU Gloss Film, TPU Matte Film, TPU Metallic Film and many more Car Color Wraps all with self-healing TPU material very good stretchable, anti-scratches, imported glue.


*Provide paint protection film (TPU) and achieve car color change at an affordable price! This is an excellent solution for protecting the surface of your car, reducing repair costs.
*Car paint can be damaged and withered by harmful rays. After using TPU, it will age naturally and will not change color for a long time.
*Providing a paint protection film on the surface of your car will have no side effects. If you wish to remove the TPU layer, it can be done without any damage to the vehicle.
*This is the ideal solution for protecting your car from bugs and wear and tear.
*The paint protection layer is invisible so it enhances the appearance. It can also wash and clean the car.
*Small scratches on the TPU will heal themselves when the TPU reaches the proper temperature.
*You can give a standardized look and make it look polished and shiny by applying a PPF protective layer.
*It is durable and easy to install.
