- Using high-quality HR202 humidity sensor. The comparator output signal is clean, good waveform, driving ability, more than 15mA
- The humidity sensor module is sensitive to environmental humidity, generally used to detect ambient humidity by adjusting the potentiometer, for detecting the humidity can change the threshold ( i.e. the humidity control), such as the need to control the ambient humidity of 60% ,then the corresponding module is transferred to the green light and humidity environment , DO high power output when flat, humidity values below this setting, high output, the green light does not shine
- DO output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting the humidity changes in the environment.
- DO output of the relay module can directly drive the shop, which can form a humidity switch, control-related equipment to work in the right environment.
- Small plates AO analog output modules can be connected OUR AD through the AD converter, you can get a more accurate numerical ambient humidity With the screw holes of 3mm, easy fixed installation.

BC557 PNP General Purpose Transistor 45V 100mA TO-92 Package
Original price was: ₹5.00.₹1.17Current price is: ₹1.17. + GSTAdd to cartBC557 is a widely used PNP bipolar junction transistor manufactured in small TO-92 package. It is a general purpose PNP transistor that can be used as a switch or amplifier in electronic circuits. Its HFE ratings are 125 to 800 which makes it an ideal transistor to use as a small signal amplifier in electronic circuits for example for audio signal amplification or other, the HFE ratings of BC557 can be determined by the last letter after its number for example BC557A HFE ratings are 110-220, BC557B HFE ratings are 200-450 and BC557C HFE ratings are 420-800. The max collector dissipation is 500 milliwatt which is also an another good point to use it in amplification stages. Moreover it will also perform well when used it as a switch for load under 100mA. The transistor has also good collector to emitter (VCE) value that is -45V, therefore you can easily use it in circuits using 40 to 45 volts DC.
