Everything nRF52840 | MySensors Forum

I'm still striggling with the nRF52840 and the low power sleep. So far I'm far away from the to 5uA in sleep mode. Maybe someone has a good example for a sleep, internal timer wake-up. The mysensors project I'm using has 1,5mA in sleep and 15mA during sensor read and send. That is …

Particle sht3x-i2c

sht3x-i2c Library. A library to interface a Particle device to an SHT31 temperature and humidity sensor using I2C. Usage. The SHT31 has two modes that can be used for reading temperature and humidity: Single Shot: the Particle device will send a command to the sensor, wait for the measurement to complete, and then read the values.

using MAX30102 - Sensors - Arduino Forum

May 06, 2021· The I2C pins are 20 and 21, but you might prefer to use the pins marked “SDA” and “SCL”, simply because this is less confusing. It makes no functional difference whether you use 20/21 or SDA/SCL because they are electrically connected. Note that on the MKR WiFi 1010, A4 and A5 are not the I2C pins. The I2C pins are 11 and 12.

Tutorial: How to Configure I²C Sensors with Arduino Code ...

Nov 03, 2017· The great strength of I2C is that you can put so many sensors on the same four wires. But for units with several pre-made modules connected you might have to remove a few smd resistors from the breakouts, or the pull-up on the bus might become too of the time I just leave them on, so I can extend the wire length, or crank up the bus clock…

Xenon cannot read the MS5803-14BA sensor - Particle

Nov 27, 2018· The below code compiles ok in the Particle IDE. It also runs perfectly on an Arduino Mega2560. (I just tried it again.) The xenon does not read data from the sensor. I have the appropriate pins connected to SDA and SCL, with 10k pullups to Same breadboard as used with the Arduino, about 4" from the Ethernet featherwing. I have a nice scl pulse and data on the sda signal as …

MAX 30102 an Arduino DUE - Sensors - Arduino Forum

May 06, 2021· Hi, I've seen projects using an Arduino UNO and a MAX 30102 (or 30100). The library that works is the one from Sparkfun (example #8). When that example is loaded into an Arduino UNO, it shows a message that the memory is almost full and that stabality problems may occur. When visualizing the data (Heart rate and SPO2 values), those are a little out of my expectations (heart rate values of …
