232-port 4-channel 10-bit A/D voltage recorder, data can be directly collected by EXCELL [Copy link]

This voltage recorder consumes very little power, does not need an additional power supply, is powered directly by port 232, has 4 channels with 10-bit accuracy, and is composed of a TINY15. Since the RESET pin is used as an A/D input, it cannot be downloaded and programmed using the ISP method, and must be programmed using a high-voltage programmer. The original source of this production is a Japanese website, which records four channels of temperature data. As long as the thermistor and pull-up resistor in the circuit diagram are removed, it will be a four-channel voltage recorder. The advantage of this production is that it does not require a dedicated PC program, and you can compile EXCELL to collect and process data and generate various charts
