Description
Product Overview
The SparkFun OpenScale is an open-source device engineered for accurate weight and temperature measurement, compatible with multiple types of load cells. It operates at 5V with a current draw of 80-100mA and includes features such as power cycling above 500ms, selectable output data rates of 10SPS or 80SPS, and both local and external temperature sensors. The device utilizes an ATmega328P microcontroller for data communication, an HX711 24-bit ADC for high-precision weight scaling, and a TMP102 sensor for ambient temperature recording. With dimensions of 3.94 x 0.59 x 2.95 inches and a weight of 0.48 ounces, it is compact and suitable for integration into various systems. Communication is handled via TTL levels at 9,600bps by default, with configurable baud rates ranging from 1,200bps to 1,000,000bps, and it supports USB to serial connections through an FT231 chip.
