Need a data acquisition recorder? The first question isn't brand or price; it's which physical inputs the logger should capture. Motion, GPS, temperature, and humidity lead to different hardware choices, and the four options here show that spread clearly. Listed prices run from $96.99 to $325.00, with a compact motion logger at one end and an eight-channel thermocouple unit at the other.
Quick Take
The WITMOTION WT901SDCL-BT50 is the motion-and-orientation option, with Bluetooth 5.0 and a 16GB SD card. Racebox Micro is the GPS speed meter and telemetry logger. The Dickson TWP is a touchscreen temperature/humidity logger, and the Pico Technology TC-08 is a USB thermocouple data logger. Start by matching the sensor type to your task, then use the listed price as the tiebreaker.

Product Notes
9-Axis Offline Accelerometer Data Logger】WT901SDCL-BT50 Bluetooth 5.0 Remote
Most useful for portable motion logging, this open-box WITMOTION unit combines Bluetooth 5.0 with a built-in 16GB SD card, so it can record even without a live connection. The sensor outputs pitch, roll, and yaw angles, acceleration, gyroscope, and magnetic-field data at up to 200Hz, with an XY angle accuracy of 0.05° noted in the title. It uses a Type-C interface and includes one 16GB SD card. At $96.99, it is the lowest listed price in this group. The open-box condition is the trade-off, and battery life is listed at about 10 hours.
Racebox Micro GPS Speed Meter \u0026 Telemetry Data Logger [BOX001
The Racebox Micro is the GPS-focused choice in this lineup. It is listed as new and built around a 25Hz GNSS receiver that the description says delivers ten-centimeter measurement precision. It supports both the Racebox Protocol and NMEA over Bluetooth, and the description points to built-in storage and API documentation for DIY projects. At $129.99, it falls between the WITMOTION and the temperature loggers in price. Its limitation is scope: this is a GPS speed meter and telemetry logger, so temperature, acceleration, and humidity are outside its listed job.
Pico Technology USB TC-08 Thermocouple Data Logger (Model PP222) - New/Open Box
The Pico Technology TC-08 is the USB-connected bench logger in this group, listed as new/open box. The PP222 kit is built around eight thermocouple channels, and the description says it can measure low voltages up to plus or minus 70 mV using PicoLog software. It includes the data logger unit, USB cable, software disc, installation guide, and factory calibration certificate envelope. At $325.00, it has the highest listed price here. The trade-off is form factor: this is a USB-connected unit for a fixed setup, not a mobile recorder you can carry into the field.
DICKSON TWP DICKSONONE TOUCHSCREEN TEMPERATURE/HUMIDITY DATA LOGGER \u0026 RTRH PROBE
The Dickson TWP is the touchscreen temperature/humidity logger in this set. It is listed as used, and the description mentions an 8-inch capacitive touchscreen, customizable views, alarms, cloud-based DicksonOne access, and a remote RTRH probe. The important caveat is that full functionality requires a separate service agreement with Dickson, which is not included with this piece. At $199.73, its listed price lands between the Racebox Micro and the Pico TC-08. If you want a large display with cloud access, this is the direction to look; if you want a simple recorder with no extra agreement, the other options may be more direct.
Final Recommendation by Use Case
- For motion, orientation, and magnetic-field logging, the WITMOTION WT901SDCL-BT50 covers the widest sensor set in a compact, SD-card recorder.
- For GPS speed and telemetry projects, Racebox Micro gives you a standalone GNSS logger with Bluetooth output.
- For temperature/humidity monitoring with a touchscreen and cloud access, the Dickson TWP is the right match, provided you accept the Dickson agreement requirement.
- For multi-channel thermocouple temperature and low-voltage logging from a computer, the Pico Technology TC-08 is the USB option.
The key is to choose the data acquisition recorder by the physical measurement you actually need; the listed prices here just help you place the options.
