SHT4X temperature and humidity sensor for the ESP-IDF
readme
# SHT4x temperature and humidity sensor driver
The SHT4x is a digital sensor platform for measuring relative humidity and temperature with various accuracy options. It uses an ultra-low power I2C interface (0.4 μW) with multiple preconfigured addresses.
The sensor has an internal heater with three levels for challenging environments and comes in a four-pin SMT-compatible package with options for a PTFE membrane or protective cover. Calibration certificates compliant with ISO17025, identifiable by unique serial numbers, are also available.
## How to use
```c
void sht4x_read_task(void *pvParameters)
{
float temperature, humidity;
while (1) {
esp_err_t err = sht4x_start_measurement(sht4x_handle, SHT4X_CMD_READ_MEASUREMENT_HIGH);
vTaskDelay(pdMS_TO_TICKS(50));
err = sht4x_read_measurement(sht4x_handle, &temperature, &humidity);
if (err == ESP_OK) {
ESP_LOGI(TAG, "Temperature: %.2f C, Humidity: %.2f %%", temperature, humidity);
} else {
ESP_LOGE(TAG, "Failed to read temperature and humidity");
}
vTaskDelay(pdMS_TO_TICKS(1000));
}
}
```
