Wireless data logger for thermal validation systems

This paper describes the software and hardware approach for building a wireless data logger for thermal validation systems. It must meet international and European regulations for validation of pharmaceutical, biotechnology and medical device (EN 285, EN 554, HTM 2010). The temperature range is from -60°C to 150°C with total system measurement accuracy of 0.1°C for all range of measurements. These equipments must measure and function in the specified temperature range.
