The TRE37 measures and records the conditions under which goods are transported, tracing shocks and variations in temperature and humidity.
Each event is time-stamped. The data can be downloaded and analysed on a PC.
The TRE37 can be used in two distinct modes:
Live/Record: Before sending the parcel, the user activates the "record" mode. As soon as it is activated, the TRE stores the values in its memory. The recorded data can be read using RF Monitor. At the end of transport, the user stops recording and can retrieve the data from memory.
Monitoring (real-time monitoring applications): The TRE sends measured data to the PC in real time. If communication is not possible, the logger stores the data in memory and sends it as soon as a connection is possible.
A silent mode can be used for air transport. In this case, to retrieve the recorded data, it will be necessary to use the "find products in silent mode" function in the RF Monitor software.
It is equipped with :

| Accelerometer | Temperature | Humidity | Brigtness | |
| TRE37 | -16g to +16g on 3 axes | -40°C to 85°C | 0… 100%RH | ------ |
| Shock sensor | 1 accelerometer that measures on 3 axes (XYZ) |
| Measurement Range | Shock : -16g to +16g on each axis
Minimum threshold : -1g to +1g on each axis (XYZ) |
| Resolution | 14 bit-3.9 mg |
| Accuracy at 25°C | ±0.5g from -16g to +16g (without resonance)
If the shok is too hight over this range, the TRE at 16g, and will record the measurement. |
| Noise | 65 mg |
| Calibration | Calibration carried out at the factory by the manufacturer |
| Drift of accuracy | Possible drift of 10 mg/year on each axis for 4 years. Not guaranteed after 4 years. |
| Bandwidth | 1600 Hz |
| Temperature sensor | |
| Measuring range | -40°C to 85°C |
| Accuracy | ± 0.2°C for (0… 60°C) |
| Resolution | 0.015°C |
| Response time | <10 seconds |
| Long-term drift | <0…05K / year |
| Humidity sensor | |
| Measurement range | 0… 100% RH |
| Accuracy | ± 1.8% RH (0… 80% RH) at 23°C |

Dew point max 80°C |
| Response time | <10 seconds |
| Long term drift | <0.5% RH/ year |
| Power supply | 1 Lithium Thionyl battery size A (3.6V) with connector | 1 AA Alkaline battery (1.5V) in the battery holder |
| Operating temperature range | -40°C to +60°C (up to 85°C peak) but the case may be damaged | -10°C to +50°C |
| Battery Life | At 25°C : almost 2 years | At 25°C : approximately 1 year |
| Battery Supplier | Newsteo | Any supplier |
| User replaceable | Yes, From connector to plug | Yes, Battery holder, polarity correct |
| RTC | Integrated real-time clock for timestamping measurements
Resolution : 1s
Maximum drift : 2 minutes/month at 25°C
The time is set in production |
| Operating temperature range | -40°C to 60°C with lithium batteries,
-10°C to 60°C with alkaline batteries Recommended temperature range to maximize peoduct autonomy : +5°C to 35°C |
| Flash memory | 16 Mbits flash, or 129.000 measurement blocks (shocks take 2 blocks)
For example, it allows in a single 2 years measurement campaign : - 1 inclination and temperature measurement every 15 minutes (70.080 records) - 29.000 shocks recordings |
| Wireless communication | Operates on ISM band, short range device
This device is designed for the European market (Uses the 868MHz band) |
| Antenna | Internal antenna |
| range | 100 meters in open space |
| ILS | Magnetic sensor for user actions :
- Wake up the product in hibernation mode - Taking a measurement outside the defined measurement frequency |
