*****
So far, out of all the mmWave sensors I have tested, this one has the longest detection range. Just imagine, it can detect a human target up to 25 metres away. This is the DFRobot C4001 mmWave Presence Sensor, the 25-metre version.
It can perfectly detect still humans wether they are standing still, sitting in a chair, or even still on the floor.
Now, if you do not need such a long detection distance, the 12-metre version of this same sensor is also incredibly impressive. I have already tested that model in a full dedicated video. It works with I2C and UART, supports Arduino, ESP32, ESP8266, Raspberry Pi, and it can detect human presence up to 8 metres and motion up to 12 metres.
Anyway, both sensors look completely different in design, size, and construction. The 12-metre version supports both I2C and UART, while the 25-metre version supports UART only. The number of transmitting and receiving antennas is also different in both versions.
The 25-metre model has more antennas, which means a stronger signal, better sensitivity, and a much longer detection range. More antennas allow it to pick up weaker reflections from distant targets, especially humans, even when the movement is minimal. This is one of the key reasons why the 25-metre version can easily outperform the 12-metre version.
Their working principle is the same, and both sensors use the same library. I have already explained the library installation process in the 12-metre version video. Both sensors are capable of monitoring:
• Number of targets
• Target speed
• Target distance
• Target energy!
It works where PIR sensors fail — detecting subtle motion, measuring distance and speed, and staying rock-solid in any environment.
