Why does my BME280 sensor not start correctly if i control its power with a mosfet?
This is the best library I've seen for the SHT31 (also 30 and 35 as mentioned) https://github.com/RobTillaart/SHT31 (he has one for the SHT85 mentioned in readme, never used it though but this guy does leagues better than any other libraries so I trust it)

NodeMCU 1 Smoking diode after plugging in DHT 11
SHT20, SHT30, SHT31, SHT35, SHT85 are the best humidity/temp sensors that exist. I'd get a 31 or 35, if you want the best you can get an 85 but they're not worth the price imo. Here's a good library on the bottom of the readme you can see some of the special capabilities https://github.com/RobTillaart/SHT31 (like the wake up which only these sensors have)

Using MPU6050 to get orientation
There are a few libraries. A popular, easy to use library is the Adafruit Unified Sensor Library collection that exposes an interface for BNO055 and other similar hardware. You can read it as a quaternion format (better for math geeks who like stable orientation) or as a rotation on X/Y/Z axes in either degrees or radians for people who aren't bothered by issues like gimbal lock when you hit a pure up or pure down orientation.

Need help with DHT22. If the temperature reaches below 0.00C I get a value of -3276.70C. Code in description and more info.

Why does it say "Failed to read from DHT sensor!" ill post the code down in the commments
// REQUIRES the following Arduino libraries: // - DHT Sensor Library: https://github.com/adafruit/DHT-sensor-library // - Adafruit Unified Sensor Lib: https://github.com/adafruit/Adafruit_Sensor

A confusing issue with NodeMCU
// Example testing sketch for various DHT humidity/temperature sensors // Written by ladyada, public domain // REQUIRES the following Arduino libraries: // - DHT Sensor Library: https://github.com/adafruit/DHT-sensor-library // - Adafruit Unified Sensor Lib: https://github.com/adafruit/Adafruit_Sensor #include "DHT.h" #define DHTPIN 4 // Digital pin connected to the DHT sensor // Feather HUZZAH ESP8266 note: use pins 3, 4, 5, 12, 13 or 14 -- // Pin 15 can work but DHT must be disconnected during program upload. // Uncomment whatever type you're using! #define DHTTYPE DHT11 // DHT 11 //#define DHTTYPE DHT22 // DHT 22 (AM2302), AM2321 //#define DHTTYPE DHT21 // DHT 21 (AM2301) // Connect pin 1 (on the left) of the sensor to +5V // NOTE: If using a board with 3.3V logic like an Arduino Due connect pin 1 // to 3.3V instead of 5V! // Connect pin 2 of the sensor to whatever your DHTPIN is // Connect pin 3 (on the right) of the sensor to GROUND (if your sensor has 3 pins) // Connect pin 4 (on the right) of the sensor to GROUND and leave the pin 3 EMPTY (if your sensor has 4 pins) // Connect a 10K resistor from pin 2 (data) to pin 1 (power) of the sensor // Initialize DHT sensor. // Note that older versions of this library took an optional third parameter to // tweak the timings for faster processors.
