Choosing between sensors, modules & components is mainly about matching the measurement job to the module. A voltage-focused Arduino project needs a different starting point than a build centered on miniature distance measurement. The 0-25V Voltage Sensor Module and BTLIFE TFS20-L LiDAR are therefore not interchangeable picks: one is framed around voltage detection, while the other is built for single-point ranging.
Quick verdict
Choose the 0-25V Voltage Sensor Module for Arduino DIY and smart-electronics projects that need voltage detection. Choose the BTLIFE TFS20-L Miniature LiDAR Sensor Module when distance measurement, a compact form, and a UART, IIC, or I2C connection are central to the build. The voltage module is USD 14.24 lower, but the measurement task-not a generic feature count-should decide.

Product notes
0-25V Voltage Sensor Module

The 0-25V Voltage Sensor Module is the direct match for Arduino DIY work centered on voltage detection. Its description specifies an input span from 0.02445V to 25V and a resolution of 0.00489V, giving the module a clearly defined measurement role. The title also places it in smart electronics projects, which makes the use case straightforward for makers planning a voltage-focused build. Its limitation is specialization: the module is framed around voltage sensing, so it is less aligned with a project whose main requirement is single-point distance measurement. Choose it when the project brief calls for voltage readings and the stated resolution is relevant to the design.
BTLIFE TFS20-L Miniature LiDAR Sensor Module

BTLIFE TFS20-L Miniature LiDAR Sensor Module earns its place when the build is about distance rather than voltage. The description identifies a fully integrated single-point dToF ranging module with a compact design, reflectivity correction, and performance in strong ambient light. Those details give it a clear role in miniature distance-measurement work, including the drone application named for the module. Its limitation is specialization in the other direction: single-point ranging is not the natural fit for a project whose central task is voltage detection. Pick it when the design calls for the TFS20-L distance-measurement format and its listed environmental and compact-design features are useful.
Final choice by use case
For Arduino DIY projects that need voltage detection, the 0-25V Voltage Sensor Module is the clearer choice. Its specified measurement range and resolution directly match that job. For a miniature distance build, especially one organized around UART, IIC, or I2C, choose the BTLIFE TFS20-L Miniature LiDAR Sensor Module. If the two use cases are both possible, let the project requirement lead: the $14.24 price spread matters, but neither module replaces the other's core measurement role.
