DFRobot and Sensirion Launch Gravity SFA40 Formaldehyde Module at $49.50

DFRobot and Sensirion launched the Gravity: SFA40 Formaldehyde Module on November 12, 2026, priced at $49.50. PR Newswire said the module combines Sensirion's electrochemical sensing with DFRobot's Gravity modular ecosystem.

Inside the SFA40 Formaldehyde Module

The module is built around Sensirion's SFA40 sensing chip and measures 0–1000 ppb, with typical accuracy of ±20 ppb or ±20% of reading within the 0–200 ppb range. Cross-sensitivity to ethanol is below 0.3%, which the companies say avoids interference from odors such as alcohol and perfume. An integrated SHT4X temperature and humidity sensor provides automatic environmental compensation.

The module uses a standard Gravity 4-Pin interface for integration with development platforms such as Arduino and Raspberry Pi. It offers an SCI firmware version for serial data reading, compatibility with Mind+ graphical programming software, and Arduino and Python libraries. DFRobot lists applications in smart home monitoring, air purifiers, building ventilation for offices, schools and public spaces, and portable detectors.

DFRobot Marketing Director Ashley Gong said: "This collaboration with Sensirion addresses a key market need—air quality detection moving toward precise quantification." Dong Zhihong, Channel Manager at Sensirion, said: "This partnership marks a key step in making precise quantification sensing more accessible."

Sensirion announced global availability of the single-use SFM3304-D gas flow sensor for medical ventilation and nebulization, according to Simply Wall St. The company said it will exhibit at electronica 2026 in Munich from November 10 to 13, showcasing sensor technologies for consumer electronics, HVAC, mobility and medical applications, Business & Financial reported.

DFRobot's Sensor Line and Distribution Reach

DFRobot showcases nearly 100 sensor products at events, including mmWave radar sensors, industrial environmental and gas sensors, ultrasonic sensors with IP68 protection and water quality sensors, according to akta.pro company records. The US warehouse alone offers over 900 popular products. The company's products are sold globally through dfrobot.com and distributors including DigiKey.

Earlier DFRobot Product Launches

DFRobot announced the seeMote Cap, a spatial tracking module for Apple Vision Pro, available for preorder at $229 with first orders shipping in late September, PR Newswire reported in September 2026. In August 2026, DFRobot launched the seeMote Cube, a handheld spatial input device with 6DOF spatial motion tracking, six programmable buttons and haptic feedback for visionOS applications, Third News reported. Wccftech reported in November 2026 that DFRobot's DX-M1 is an M.2 AI accelerator offering 25 TOPS of INT8 compute at 2-5W power for $139.

The Gravity: SFA40 Formaldehyde Module is available for purchase on the official DFRobot online store, priced at $49.50.
