APASENSE v1.1.1

Added

• Library logo added to extras/apasense-logo.png — now displayed in README header.
• Alternative logo variant in extras/apasense-logo2.png.

APASENSE v1.1.0

What's new

Alert melody patterns

Three severity-matched buzzer rhythm patterns stored in flash (PROGMEM):

• BUZZER_INFO — single beep (1.0 s cycle)
• BUZZER_WARNING — double beep (2.55 s cycle)
• BUZZER_ALARM — triple fast beep (1.95 s cycle)

alert(severity, repeat=false) plays once or loops until stopAlert(). Designed for APAPUMP alarm callbacks.

Power calculation

enableCurrent() gains an optional voltageV parameter. getPower() returns apparent power in VA (V × I RMS). Use APASENSE_MAINS_EU (230 V) or APASENSE_MAINS_US (120 V).

Changes

• setBuzzer(false) and beep() now cancel any active alert() pattern
• Timer comparisons made rollover-safe (49-day millis() overflow fix)
• SRAM: 57 bytes (+6 vs v1.0.0)

APASENSE v1.0.0

Initial release

ADS1015 analog sensing and PCF8574AT I/O library for APA pool automation.

What's included

• Pressure transducer reading with auto zero-calibration and EEPROM persistence
• AC current measurement via ACS712 — true RMS, non-blocking 32-sample accumulator
• Solar irradiance (LDR) — 0–100 %, user-supplied calibration constants
• AUX raw voltage input
• PCF8574AT: 4 × tank-empty sensor inputs (configurable polarity) + 4 × status LEDs
• Buzzer management — direct GPIO, non-blocking timed beep
• Pure Wire.h dependency — no Adafruit or external libraries
• 5-platform verified: AVR Uno, Mega 2560, ESP32, ESP8266, STM32
• 4 examples including LDR calibration tool and full APAPUMP + APADOSE integration
