One useful property of these sensors is that their nominal accuracy is excellent (±0.1 °C), which is necessary for some scientific applications (e.g., ensuring precise *and* accurate control of a chemical reaction's temperature).\n\nThe pyboard implementation is based on IRQs and a Timer, and seems to work reliably.\n\nThe esp32 implementation is also based on IRQs and a Timer. It stores a buffer of the 15 past readings and reports a temperature corresponding to the median of these readings. To change the buffer length, simply edit `MEM_LEN` and `MEM_HALF_LEN in `zacwire.py`.\n\nThe RP2040 implementation uses two PIO state machines and also seems quite reliable.
