Abstract:In response to the needs of high-precision temperature monitoring in biochemical inspection laboratories, a set of high-precision wireless temperature monitoring systems are designed and implemented. The temperature collector is based on the ATMEGA128 CPU and uses PT100 as the sensor to achieve ±0.1℃ Measurement accuracy, data is transmitted wirelessly via Wi-Fi. Data acquisition and monitoring system is developed based on .NET Framework 4.6 framework with C# language. The experimental results show that the system runs stably and the measurement accuracy meets the requirements.
