description PREMISE: High‐precision data acquisition (DAQ) is essential for developing new methods in the plant sciences. Commercial high‐resolution DAQ systems are cost prohibitive, whereas the less expensive systems that are currently available lack the resolution and precision required for many physiological measurements. METHODS AND RESULTS: We developed the software libraries, called piadcs, and hardware design for a DAQ system based on an ultra‐high‐resolution analog‐to‐digital converter and a Raspberry Pi computer. We tested the system precision with and without a thermocouple attached and found the precision with the sensor to be better than ±0.01°C and the maximum possible system resolution to be 0.4 ppm. CONCLUSIONS: The ultra‐high‐resolution DAQ system described here is inexpensive, flexible enough to be used with many different sensors, and can be built by researchers with rudimentary electronic and computer skills. This system is most applicable in the development of new measurement techniques and the improvement of existing methods.
