{"title":"OpenScale IoT Wireless Load Cell Scale Controller","handle":"sparkfun-openscale-iot","url":"/products/sparkfun-openscale-iot","description":"Build a connected weighing system without starting from low-level load cell code. OpenScale IoT is a wireless scale controller built around the ESP32-PICO-MINI, designed to turn a standard load cell setup into a configurable, connected weigh scale.Attach a four or five-wire load cell, or use four load sensors in a Wheatstone bridge arrangement, then configure calibration, sample rates and precision through a terminal menu. You can access it over Bluetooth/BLE, USB-C wired serial, or a serial port connection.For connected projects, the board can join a local 2.4GHz WiFi network for live data viewing and Over-The-Air firmware updates. It also includes a Qwiic connector for solder-free I2C expansion, an onboard TMP102 temperature sensor, and a 3-pin screw terminal for an external one-wire temperature probe at the measurement site.Documentation and design resources include a schematic, KiCad files, board dimensions, hookup guide, HX711 and TMP102 datasheets, firmware binaries and a GitHub repository.Features:Bluetooth & Wired Config: Connect via Bluetooth/BLE or a wired USB-C/serial connection to access the terminal menu at 115,200bps. Terminal configuration via Bluetooth is not supported on Apple devices.WiFi Integration: Connect the board to your local 2.4GHz WiFi network to view your live data and perform Over-The-Air (OTA) firmware updates.Qwiic Expansion: Easily add additional I2C sensors and displays to your project using the integrated Qwiic connector. No soldering required.ESP32-PICO-MINI Module2.4GHz WiFi, Bluetooth®, and Bluetooth LE supportedOn-Chip PCB antennaSerial configuration menu supported over wired and Bluetooth connectionsOver-the-Air (OTA) firmware updates with WiFi connectionOn Board & External Temperature SensorsFixed & Adjustable GainSpecifications:Operating Voltage: 5VOperating Amperage: 80-100mAPower Cycling: above 500msSelectable Output Data Rate: 10SPS or 80SPSIt is suited to long-running static load monitoring, DIY scales, beehive monitoring, conveyor applications, coffee measurement and other projects where ongoing weight and ambient temperature data are useful.","vendor":"SparkFun","product_type":"Load Cell Controller","in_stock":true,"options":[],"variants":[{"id":15745,"title":"Default Title","sku":"SF-SEN-30282","mpn":"SEN-30282","price":82.9,"on_sale":false,"in_stock":true,"available_quantity":51}]}
