+# TFMini-S Time of Flight Distance Sensor for ESPHome
+
+This is an external component for ESPHome that supports the TFMini-S time of flight distance sensor.
+
+## Installation
+
+You can install this component in two ways:
+
+### 1. Using ESPHome external components
+
+```yaml
+external_components:
+  - source: github://your-username/esphome-tfmini@main
+    components: [ tfmini ]
+```
+
+### 2. Manual installation
+
+Clone this repository into your ESPHome `custom_components` directory:
+
+```bash
+cd <your config directory>/custom_components
+git clone https://github.com/your-username/esphome-tfmini.git
+```
+
+## Configuration
+
+Add the following to your ESPHome configuration file:
+
+```yaml
+# Example configuration
+uart:
+  tx_pin: GPIO17
+  rx_pin: GPIO16
+  baud_rate: 115200
+
+sensor:
+  - platform: tfmini
+    name: "Distance Sensor"
+    update_interval: 1s
+```
+
+## Features
+
+- Measures distance in meters
+- Automatic configuration of the TFMini-S sensor
+- Signal strength validation
+- Temperature monitoring (internal, not exposed yet)
+
+## Notes
+
+- The sensor is configured to use the standard 9-byte output format
+- Refresh rate is set to 100Hz
+- Data is provided in meters with 2 decimal precision
