MICROSOFT DEVELOPS BLOOD PRESSURE MONITORING GLASSES

Medical conditions, specifically hypertension and heart problems require at-home blood pressure monitoring devices, and if you have frequent high blood pressure, you may need to monitor your blood pressure constantly. The use of devices like blood pressure inflatable cuffs can be inconvenient and strenuous, but this could change. With the new Microsoft Glabella project glasses you can continuously monitor y ...

Save My Child: The smart sensor that sends text messages if you forget the child in the car

It is installed in cars, and thanks to a detector placed on the child seat, it warns us – via SMS or phone call – if we get away without bringing the child with us. Among the most saddening (and at any rate, infrequent) accidents in the news, there are those of parents that – because of briskness, health problems or lack of attention – get out of the car and “forget” their kids on the child seat, in a hot o ...

Tiny Solar Energy Module (TSEM)

Description This is a 1x1 inch PCB module with two tiny solar cells, a highly efficient Li-Ion battery charger and with two regulated outputs (3.3V and 1.8V). It harvests enough power from indoor light to power a simple BLE or LoRa sensor. The board has castellated vias so it can be surface mount soldered onto a mother PCB as well as soldered onto 0.1" headers to be used in a bread board. Based on TSEM I de ...

Particle sensor with LoRa

Two PCBs from earlier projects were used in this project: LoRa breakout board Sensor PCB with Si7013 humidity sensor from multisensor LoRa project … and particle sensor. Particle sensors could be cheap and easy to use. Disadvantage of lowest cost PM sensors is lack of “calibration”. The best method to measure particle content dispensed in the air is to collect the air sample and analyse it off-line in the l ...

Interfacing LM35 temperature sensor with PIC18F4550 microcontroller

Interfacing PIC18F4550 with LM35 This small topic shows the circuit diagram and CCS C code of the interfacing of LM35 temperature sensor with PIC18F4550 microcontroller. The LM35 temperature sensor is three pin device (VCC, OUT and GND) with an output voltage linearly related to Centigrade temperature. Since the LM35 output varies with dependent to the temperature we need ADC (Analog-to-Digital Converter) m ...
