At present, with the increasing awareness of environmental protection, many families are paying more and more attention to kitchen waste disposal, and household electric composters have come into being. By crushing kitchen waste and converting it into organic fertilizer, electric composters effectively reduce the burden on people to dispose of kitchen waste. In the working process of the electric composter, the NTC temperature sensor will use its own temperature perception to ensure that the microbial decomposition process is carried out within the optimal temperature range to ensure the work efficiency of the electric composter.

The core feature of the NTC temperature sensor is that its resistance value decreases with increasing temperature, and this nonlinear relationship enables it to monitor the internal temperature changes in real time during the operation of the household electric composter. Combined with other modules of the electric composter, such as information acquisition module, control module, output/input module, etc., it can not only provide a better decomposition environment for kitchen waste, but also improve the sterilization efficiency of the electric composter. Specifically:

First, accurate temperature monitoring to ensure the treatment effect

The microbial decomposition process of the electric composter has very strict temperature requirements, usually need to be maintained between 35℃~60℃ (Reference: Journal of Environmental Engineering, 2021), so that the activity of microorganisms can be fully guaranteed, so as to achieve efficient treatment and decomposition of kitchen waste. If the temperature is too high, it will affect the microbial activity and greatly reduce the treatment effect; If the temperature is too low, the decomposition rate will be affected, resulting in a decrease in the efficiency of kitchen waste treatment.

Therefore, after the electric composter is started, the NTC temperature sensor will synchronize the internal temperature status monitoring. Through the information acquisition module, the NTC converts its resistance value into the corresponding electrical signal and transmits it to the control module, the control module sends a command according to the signal, and the output/input module receives the command and adjusts the temperature. The accurate temperature monitoring of the NTC temperature sensor significantly improves the work efficiency of the electric composter and provides users with a stable and high-quality user experience.

Second, overheating protection, prolong the life of the electric composter

Prolonged overheating operation will not only accelerate the aging and wear of key components of electric composter, but also may cause circuit failures and even potential safety hazards. The NTC temperature sensor works in tandem with the control module to provide reliable overheating protection for electric composter. When the NTC detects that the internal temperature of the electric composter exceeds a preset safety threshold, the change in its resistance value is quickly transmitted to the control module. After receiving this signal, the control module will immediately trigger the overheating protection mechanism, such as reducing the speed of the motor to reduce the heat generated during the kitchen waste treatment process; Or temporarily cut off the power supply to avoid further temperature rises. With the help of the NTC temperature sensor, the dynamic adjustment of the electric composter not only improves the decomposition efficiency, but also extends its own service life.

Third, optimize fertilizer treatment, improve nutrient transformation

In the process of converting kitchen waste into fertilizer by electric composter, the decomposition and transformation of each stage have strict requirements for temperature. In the initial stage of rapid decomposition, appropriate high temperature (such as 50℃~55℃) can accelerate the reproduction and metabolism of microorganisms, and promote the rapid decomposition of macromolecular organic matter into small molecule substances. In the later stage of decomposition, stable low temperature (such as 40℃~45℃) is conducive to the growth of beneficial microorganisms and the accumulation of metabolites, and improves the nutritional value of fertilizer. The NTC temperature sensor feeds the signal back to the control module through high-accuracy temperature monitoring and control, ensuring that the entire fertilizer treatment process is carried out under more suitable temperature conditions.

With the continuous progress of smart home technology and the continuous improvement of people's pursuit of environmental protection, the household electric composter market is ushering in a broader development space. In order to meet the performance upgrade of electric composter, EXSENSE Electronics Technology Co., Ltd. recommends the use of TS series excellent-reliability NTC temperature sensor, which high accuracy can help the electric composter improve the accuracy of its own temperature monitoring and complete excellent kitchen waste treatment work. EXSENSE's NTC temperature sensor also has high sensitivity characteristics, which can maintain a fast response during the working process of the electric composter, helping it to achieve efficient kitchen waste treatment.
