Small Size
TFmini Plus solid state lidar features a tiny size of 35*21*18.5mm (1.38*0.83*1.73”), as large as a man’s finger, but it brings us excellent ranging performance.
High Performance
Detection distance
TFmini Plus is a short to medium range TOF radar.It's detection distance is up to 12m, the blind zone is 10cm, resolution is 5mm and signal acceptance angle is 3.6°.
Minimum edge length of 6 cm within a detection distance of 1m; Minimum edge length of 72 cm within a detection distance of 12m.
Schematics of the range of distance measurement and effectiveness of the product
Minimum side length for effective detection corresponds to detecting range
Easy to Start
This TOF Lidar sensor works well with all sorts of Arduino controllers. It can be easily integrated into the system when used with the Arduino library developed by DFRobot.
Safer and More Stable
What is TOF?
TFmini Plus is based on TOF, namely, Time of Flight principle. To be specific, the product emits modulation wave of near infrared ray on a periodic basis, which will be reflected after contacting object. The product obtains the time of flight by measuring round-trip phase difference and then calculates relative range between the product and the detection object.
TFmini Plus is a small single-point solid state LiDAR with unique optical and electrical algorithms that can realize accurate and quick distance measurement as well as keep a stable and high-sensitive performance.
2. This product itself has no polarity and over-voltage protection. Please properly connect and supply power as described in this manual.
3.Operating temperature of this product is between -20℃ and 60℃. Do not use it beyond this temperature range to prevent malfunction.
4. Storage temperature of this product is between -20℃ and 75℃. Do not store it beyond this temperature range to prevent malfunction.
5. For ensuring the product performance, do not open the product shell to do any adjustment or maintenance against the instruction.
6. Detecting object with high reflectivity, such as the mirror or the smooth floor tile, may cause a system malfunction.
7. The product will malfunction if there is any transparent object between it and the detecting object, such as glass or water.
8. The product will malfunction if its emitting or receiving IR-pass filter is covered by the dust. Please keep the IR-pass filters clean. Please do not spread ethyl alcohol on the IR-pass filters, which are made of acrylic, IR-pass filters will be damaged.
9. Please do not pull the fine wire, the wire may be damaged.
10. Please always send the command of save settings when try to modify parameters of TFmini Plus, otherwise the settings will not take effect. Bytes with yellow undertone“SU”represent checksum: sum of all bytes from Head to payload. Lower 8 bits.
