A small temperature alarm in Toit 2.0

Описание и применение

Пример реализации температурного сигнала с гистерезисом в Toit 2.0, демонстрирующий, как избежать частых переключений состояния при колебаниях температуры.

Задача

Implement a hysteresis-based temperature alarm that avoids rapid state changes when readings hover around threshold values.

Результат

The program printed the expected sequence of alarm states, demonstrating correct hysteresis logic without external hardware.

Рабочий процесс

• 1. Download the v2.0.0 Toit release for your platform and add its bin directory to PATH.
• 2. Verify the runtime with toit --version.
• 3. Create a file sensor.toit containing the alarm logic using local variables and conditional blocks.
• 4. Run toit analyze sensor.toit to check syntax.
• 5. Execute the program with toit run sensor.toit and observe the output.
• 6. Verify hysteresis behavior by comparing output to expected state transitions.

Доказательства

A temperature alarm needs a little memory. Switch it on at 30°C, keep it on while the reading drifts down, and switch it off at 27°C.
