- Product Name: formaldehyde gas detection sensor MQ138 (with analog and TTL level signal output)
- Size: 22mm X30mm X32mm length * width * height
- Two, the main chip: LM393, formaldehyde sensor probe
- Three, working voltage: DC 5V
- Four, characteristics:
- with the signal output indicator;
- dual signal output (analog output and TTL level output);
- TTL output valid signal is low; (the output low power signal light is bright, can be connected with the microcontroller IO port).
- the output of analog quantity increases with the increase of concentration, the higher the concentration, the higher the voltage is;
- the aldehyde, alcohol, ketone, aromatic compounds with high sensitivity;
- has a long life and reliable stability;
- fast response recovery characteristics;
- with the installation hole to facilitate the installation of fixed;
- the probe can be inserted into the design, convenient test.
