A single moment, frozen forever

“For me, a successful photograph is silent, giving you a sense of peace, making you kind and gentle, giving you courage, awakening memories of beautiful things, making you happy.”

—— 山本昌南 (Yamamoto Masao)

Indoor Environment Monitor · Last 7 Days

Temperature (line) · Humidity (bar) · Pressure (dashed) · Illuminance (orange line) | 5-min sampling: ESP32 board 1 (BME680) + ESP32-C3 board 5 (VEML7700 lux) · auto-update

⚠️ IAQ(空气质量)暂时不显示 / IAQ chart temporarily hidden:
原因:IAQ(0–500)只能由 Bosch BSEC 算法算出,而 BSEC 是闭源库(不开放源码、无开源替代、按平台发布二进制)。原先的 IAQ 数据来自香橙派 139 上的 BSEC Linux 二进制;该机与传感器已于 2026-09-23 退役,采集改由 ESP32(板1)承担,而 ESP32 侧没有可用的 BSEC → 只上传温度/湿度/气压,IAQ 暂无数据源。拿到 BSEC 的 ESP32 版后可恢复该曲线。
Reason: IAQ can only be computed by Bosch BSEC, which is closed-source (no open-source alternative; shipped as per-platform binaries). The previous IAQ source ran BSEC on an Orange Pi 139, retired on 2026-09-23. Sampling now runs on an ESP32 (board 1) with no BSEC available, so only temperature / humidity / pressure are collected. The IAQ curve can be restored once a BSEC build for ESP32 is available.
