The TH-1-SHT board is a digital temperature/humidity sensor peripheral board for microcontroller systems. It features the SHT75 sensor, and operates from a 5V source. Jumpers allow you to select which pins are connected to the I2C lines of the sensor.
Note: The same PCB is used for two different boards. The photo here shows the other board with a different sensor and a 1-Wire bus connector installed.
The communication pins and 5V power supply connections are available on a 20-pin (2×10) expansion connector for interfacing to existing microcontroller systems. This board can be connected either as a piggyback daughterboard on a microcontroller board (one with a matching connector) using standoffs or can be placed away from the microcontroller board using a 20-wire ribbon cable.
The expansion connector is plug-in compatible with MicroTRAK, MINI-MAX and BSCB systems. You can use it in your own system too, of course; see the manual for the expansion connector's available pinout configurations that you can set via jumpers.
Temperature/Humidity Sensor Peripheral Board Features
- SHT75 humidity sensor provides ±1.8% RH accuracy from 0 to 100% RH
- 20-pin expansion connector for data communication with a microcontroller board and power supply
- Two jumper blocks to select the communication lines with a microcontroller board
- Single operating voltage: 5V DC, 3 mA maximum supply consumption
- Dimensions are 2.4 × 1.2 inches (5.88 × 2.94 cm)
- Mounting holes of 0.138 inches (3.5 mm) on the four corners
- 0° to 70° C operating, -40° to +85° C storage temperature range
If you want to chain multiple add-on boards together, you can purchase cable and connectors separately to construct daisy-chain cables that suit your setup.
