# ESPHome SEN0590 Laser Ranging Sensor Component
|
|
|
|
This is a custom component for ESPHome to integrate the DFRobot SEN0590 Laser Ranging Sensor (4m).
|
|
|
|
## Features
|
|
|
|
* Measures distances from 2cm up to 400cm.
|
|
* Uses the I2C communication protocol.
|
|
* Provides distance readings in centimeters.
|
|
* Includes error handling for communication issues and invalid readings.
|
|
|
|
## Sensor Information
|
|
|
|
* **Product Wiki:** [DFRobot Laser Ranging Sensor (4m) SKU: SEN0590](https://wiki.dfrobot.com/Laser_Ranging_Sensor_4m_SKU_SEN0590)
|
|
* **Communication:** I2C
|
|
* **I2C Address:** 0x74 (default)
|
|
* **Measurement Range:** 2cm - 400cm
|
|
* **Operating Voltage:** 3.3V - 5V
|
|

|
## Wiring
|
|
|
|
Connect the sensor to your ESP device's I2C pins:
|
|
|
|
| Sensor Wire | ESP Pin | Description |
|
|
| :---------- | :------------- | :---------------------- |
|
|
| Red (VCC) | 3.3V or 5V | Power Supply Positive |
|
|
| Black (GND) | GND | Ground |
|
|
| Yellow (SCL)| I2C SCL Pin | I2C Clock Line |
|
|
| Green (SDA) | I2C SDA Pin | I2C Data Line |
|
|
|
|
## ESPHome Configuration Example
|
|
|
|
```yaml
|
|
esphome:
|
|
name: laser_distance_test
|
|
# ... other config
|
|
|
|
# Enable I2C
|
|
i2c:
|
|
sda: GPIO21 # Adjust GPIO pins as needed
|
|
scl: GPIO22
|
|
scan: true
|
|
id: bus_a
|
|
|
|
# Add the custom component directory

|
|
|
|
# Sensor configuration
|
|
sensor:
|
|
- platform: sen0590
|
|
name: "Laser Distance"
|
|
update_interval: 100ms # Adjust as needed, min ~50ms due to sensor delay
|
|
# Optional: Specify a different I2C address if changed
|
|
# address: 0x75
|
|
|
|
|
|
## Usage
|
|
The sensor will report the measured distance in centimeters. The `update_interval` should be set considering the sensor's response time (around 19-38ms plus the 50ms delay used in the component). Setting it too low might lead to missed readings or unstable behavior. |
