About

Thermistor Calculator

Read full description

Thermistor Calculator is a handy tool for anyone who works with thermistors. With this app, you can easily convert between resistance and temperature using two common models: the Beta model and the Steinhart-Hart model. You can also enter the parameters of your thermistor and see how it behaves under different conditions. Moreover, you can estimate the temperature readout error based on the accuracy of your measurement device and the tolerance of your thermistor. Whether you are a student, a hobbyist, or a professional, Thermistor Calculator will help you understand and use thermistors more effectively. This software can edit and save open-format .thermistor files defined here: https://github.com/ELOWRO/Thermistor-Calibration-Data-Format

About

ACI Tech Tool

Read full description

ACI Tech Tool unifies every step of ACI deployment for field engineers in one secure, Flutter-powered workspace. Scan rXg QR codes to authenticate instantly with encrypted credential storage, then capture ONTs, access points, switches, and gateways using guided multi-mode barcode workflows that validate serials, MACs, and part numbers against the centralized MAC manufacturer database. Each scan feeds straight into automated device registration that assigns hardware to PMS rooms and keeps device lifecycles synchronized. Stay on top of the install with live dashboards that surface network health, alert priorities, and quick actions, plus a comprehensive device inventory with filters, status chips, and deep detail views for notes, photos, and port layouts. The room readiness tracker shows which rooms are complete, which are blocked, and exactly what hardware or documentation is missing. Offline-aware caching, retry logic, and camera lifecycle management keep the app reliable in spotty environments, supported by extensive automated testing to deliver enterprise-grade performance for every deployment.
