Short Description
Sensirion SHT45 sensor (±0.1°C / ±1% RH) inside our ABS plastic housing. I2C interface, indoor use. Ships with 1-metre 4-core shielded cable.
Description
The T-SHT45-P combines the Sensirion SHT45 digital temperature and humidity sensor with our ABS plastic housing. The sensor measures temperature within ±0.1°C and humidity within ±1% RH and communicates over I2C at address 0x44 (default).
16×100mm grey ABS plastic body with a steel sintered filter at the tip and a 2-hole mounting bracket included. Intended for indoor use — room monitoring, HVAC return-air, server rooms, classrooms, and indoor IoT projects. The probe ships with a 1-metre 4-core shielded cable terminated in bare-tinned wire ends (Red: VCC, Black: GND, Yellow: SDA, Green: SCL) for connection to ESP32, Arduino, Raspberry Pi, STM32, or any I2C-capable host. Typical applications include indoor room monitoring, HVAC return-air, server rooms, museum and archive climate, classrooms, and indoor IoT projects.

Wiring
The probe ships with a 4-core shielded cable terminated in bare-tinned wire ends. Connect as follows for a 3.3V I2C host (ESP32, Raspberry Pi, STM32, RAK Wireless, or Arduino with level-shifter):
| Red | VCC — 3.3V supply |
| Black | GND — ground |
| Yellow | SDA — I2C data (4.7 kΩ pull-up to 3.3V recommended) |
| Green | SCL — I2C clock (4.7 kΩ pull-up to 3.3V recommended) |
Software
Compatible with the Sensirion SHT4x Arduino library, the Adafruit SHT4x library, the ESP-IDF SHT4x component, and the MicroPython sht4x driver.
Warranty
14-day replacement warranty against manufacturing defects from the date of delivery. Damage from reverse polarity, over-voltage, or use beyond the rated environmental conditions is not covered.
Frequently Asked Questions
Q: What does this probe ship with?
A: Each probe ships with a 1-metre 4-core shielded cable. The cable terminates in bare-tinned wire ends — Red (VCC), Black (GND), Yellow (SDA), Green (SCL). If you need a JST-XH or Dupont termination, leave a note on your order.
Q: What is the warranty?
A: Tarangify products carry a 14-day replacement warranty against manufacturing defects from the date of delivery. Damage from reverse polarity, over-voltage, or use beyond the rated environmental conditions is not covered.
Q: Can I order longer cable lengths?
A: Yes. 2-metre and 5-metre cables are available as paid options. Custom lengths can be made to order — contact us with your requirement.
