Short Description
Bosch BME280 sensor (±1°C / ±3% RH / ±1 hPa) inside our waterproof cable-gland housing. Measures temperature, humidity, and barometric pressure over I2C. Suitable for outdoor use. Ships with 1-metre 4-core shielded cable.
Description
The T-BME280-W combines the Bosch BME280 digital sensor — measuring temperature, humidity, and barometric pressure — with our waterproof cable-gland housing. The sensor measures temperature within ±1°C, humidity within ±3% RH, and barometric pressure within ±1 hPa and communicates over I2C at address 0x76 (default).
Brass adapter body with a sealed cable gland on top and a breathable plastic mesh filter at the sensing end. Designed for outdoor inline cable mounting where the cable run needs to be sealed against water and dust. 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 outdoor weather stations, irrigation, agriculture, greenhouse monitoring, balcony and garden sensors, and outdoor IoT networks.

| 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 Bosch BME280 driver, the Adafruit BME280 library, the ESP-IDF bme280 component, and the MicroPython bme280 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.
