STRUCT HTU31_DATA(9)

💜 struct htu31_data(9) — the Kernel API Manual, bestie edition 💜

okay so this is a page from the Kernel API Manual and it's literally all about struct htu31_data — like, the whole entire vibe bundle you need to make an HTU31 chip go ✨

---

🌸 NAME 🌸

struct htu31_data — all the data required to operate a HTU31 chip</p> 🫶 that's it, that's the whole personality.

---

🎀 SYNOPSIS 🎀

here's the shape of it, no cap, copy it exactly:

struct htu31_data {
    struct i2c_client *client;
    struct mutex lock;
    long wait_time;
    long temperature;
    long humidity;
    u8 serial_number[HTU31_SERIAL_NUMBER_LEN];
    bool heater_enable;
 };

---

🦋 Members 🦋

these are the lil fields inside, and honestly? each one is a main character:

• client — the i2c client associated with the HTU31 💫 like the sensor's plus-one, its connection to the outside world.
• lock — a mutex to prevent parallel access to the data 🔒 nobody touches the data at the same time, we do not do chaos in this house.
• wait_time — the time needed by sensor to convert values ⏳ the sensor's lil "gimme a sec" window, respect it.
• temperature — the latest temperature value in millidegrees 🌡️ yes *milli*degrees, she's precise like that.
• humidity — the latest relative humidity value in millipercent 💧 again with the milli, we stay accurate.
• serial_number — the serial number of the sensor 🏷️ of type u8, sized HTU31_SERIAL_NUMBER_LEN — that's the sensor's government name.
• heater_enable — the internal state of the heater 🔥 a bool, so it's just vibes: on or off.

💅 tiny reminder: keep the field names and types exactly as they are — I'm cute, not creative with your struct layout.
