DFRobot brought electrochemical formaldehyde sensing into a modular form with the ‘Gravity: SFA40 Formaldehyde Module,’ making it easier to drop into builds. It combines Sensirion’s SFA40 sensing chip with DFRobot’s Gravity ecosystem, giving developers and enterprises a way to measure formaldehyde with low cross-sensitivity and precise quantification.
The module adds built-in temperature and humidity compensation through an integrated SHT4X sensor, which helps stabilize readings as conditions change. It also uses a standard Gravity 4-pin interface, so it can connect quickly with Arduino and Raspberry Pi projects, while the SCI firmware version supports serial data reading without programming.
DFRobot shows how a $49.50 price on its online store and interface standardization can turn a specialized sensing task into a purchasable building block for air purifiers, ventilation control and portable detectors, making lab-style measurement easier to move into everyday devices and prototype workflows.
