Abstract
The effects of climate change on shallow lakes were studied via control experiments, such as a mesocosm study. Accurate control, monitoring and recording of temperature difference are crucial for the ongoing simulation of warming mesocosm. In this article, we provide a method that can adjust automatically and allow real-time monitoring and recording of water temperature. This system is composed of three main parts: the temperature sensor DS18B20, which measures and outputs the digital temperature value; a C8051F320 microcontroller, which acquires, analyses and stores the temperature data and performs control upon start and shutdown of external heating elements; and external heating devices perform heating until the target temperature difference is achieved.•This system can maintain a certain temperature difference under gradually changing external environmental conditions.•This system can achieve real-time online monitoring of water temperature.•This system has an excellent ability to resist disturbance.
Highlights
This recording system for controlling temperature difference can control heat devices for experiments automatically and allow real-time monitoring and recording of water temperature
A series of studies have investigated the effects of climate change on shallow lakes using different approaches, such as enclosure experiments and analysis of interannual fluctuations or differences between various climate regions [5,6,7]
Controlled experimental systems are often designed to investigate the effects of climate warming on shallow lakes [8,9,10,11] and accurate control of the temperature difference between warming and reference groups is crucial to ensuring the veracity of experimental results
