Air Quality Sensor – PM2.5, PM10
ByoeadminThis module uses the principle of optical LASER light scattering to measure the concentration of particulate matter (PM2.5 and PM10) in the air. It consists of a LASER diode, a photodiode, a microcontroller, a low-noise amplifier and a suction fan. The suctioned air passes through the detection chamber, where the LASER light striking the suspended…
Analog input extension shield for Arduino
ByoeadminThe Arduino UNO™ is equipped with 6 analog inputs. Some projects call for more analog inputs, e.g. sensor- or robot projects. This shield only uses 4 I/O lines (3 digital, 1 analog) but adds a whopping 24 inputs, so in total you have 29 analog inputs at your disposal. Features 24 analog inputs uses…
Using LoRa shield in Packet Mode
ByoeadminIn a previous post, you had the opportunity to discover a new Shield for Arduino, based on Semtech’s SX1278 chip that, in view of a very limited price, allows the implementation of a radio communication for a wide range of applications: from the transmission of digital signals in OOK or FSK mode, to the…
Breakout board with NE555
ByoeadminBreakout board based on the integrated 555 (SMD version), one of the integrated circuits that made the history of solid-state electronics. The 555 is a timer that can be configured in various ways incorporating a pair of comparators whose outputs are connected to the SET and RESET inputs of an RS flip-flop, so as to create…
GSM Remote Control – Gate Control
Part 1 – IntroductionByoeadminNow we can start describing our first application, that is, the GSM gate controller: in this modality, our system controls the relay it is equipped with whenever it receives a call from a telephone number belonging to a list of numbers previously acquired through a special procedure, which can be performed via SMS using a…
