Sensor
OMRON MEMS non-contact temperature sensor D6T-44L-06
| item | Contents |
|---|---|
| Model | D6T-44L-06 |
| Number of pixels | 16 (4x4) |
| Power-supply voltage | DC5[V] |
| image |  |
- Since the power supply voltage is DC5 [V], level conversion is required when connecting to I2C of Raspberry Pi.
- Since D6T-44L-06 is a 4x4 grid, it is difficult to recognize the human shape even if it is processed. I don't think there is any problem with temperature as a detection application.
Pololu Time-of-Flight Distance Sensor Module VL53L0X
| item | Contents |
|---|---|
| Model | VL53L0X |
| range of detection | 3 ～ 200[cm] |
| Operating voltage | DC2.6 ～ 5.5[V] |
| image |  |
- Since the power supply voltage is DC2.6 to 5.5 [v], it can be directly connected to I2C of Raspberry Pi.
BOSCH temperature / humidity / barometric pressure sensor BME280
| item | Contents |
|---|---|
| Model | BME280 |
| temperature | -40 ～ +85[℃] |
| Relative humidity | 0 ～ 100[%] |
| Barometric pressure | 300 ～ 1100[hPa] |
| Operating voltage | DC1.71 ～ 3.6[V] |
| image |  |
- Since the power supply voltage is DC 1.71 to 3.6 [V], it can be directly connected to I2C of Raspberry Pi.
- The sensor itself is manufactured by Bosch Sensortec, but it is sold by various manufacturers with a built-in board.
Distance correction for non-contact temperature sensor
The Thermo AI device TiD uses the VL53L0X to correct the measured temperature of the non-contact temperature sensor.
The Thermo AI device TiD has a program that can record the relationship between distance and temperature.
The data is recorded by this, the approximate expression is obtained by spreadsheet software, and the temperature of the distance is corrected by the approximate expression.
