Seeed Studio Studio Grove Temperature and Barometer Sensor (SPA06-003) - I2C/SPI Interface

The default I2C address is 0x77. An alternative address of 0x76 is also available, typically selectable via a configuration pin or register setting. This allows multiple sensors to operate on the same I2C bus without address conflicts.

No. The module requires a 3.3V supply voltage. Applying 5V may damage the sensor. When connecting to a 5V microcontroller, use a logic level converter for the I2C/SPI lines and ensure the VCC pin is supplied with 3.3V from a regulated source.

For SPI communication, connect the module's SPI pins (MOSI, MISO, SCK, CS) to your microcontroller's SPI port. The Chip Select (CS) pin must be pulled low to enable SPI mode. Consult the sensor datasheet for the specific command structure and data registers to initiate readings.

The FIFO (First-In-First-Out) buffer allows the sensor to store multiple pressure and temperature readings internally. The host microcontroller can put the sensor into a deep sleep mode and periodically wake to read batches of data from the FIFO, drastically reducing the average current consumption for battery-powered applications.

Yes. With its wide operating temperature range (-40°C to +85°C) and high pressure accuracy (±0.3 hPa), it is well-suited for outdoor environmental monitoring. For permanent installation, ensure the module is housed in a ventilated, waterproof enclosure to protect it from direct rain and condensation while allowing ambient pressure equalization.
