  ESPHome is a system to control your ESP8266/ESP32 by simple yet powerful configuration files and control them remotely through Home Automation systems.

  

Similar to this but maybe slightly cheaper, ESPHome using a Wemos D1 Mini (~$5) and either a BME280 (~$5-8) for temp and humidity or a Dallas sensor (~$2) with the metal ends for just temp. ESPHome will broadcast MQTT over WiFi where you can customize alerts and graphs etc.

If you want to go cheap per-sensor. Here's a tutorial on using an ESP32 (microcontroller w/ wifi) w/ a BME280 (good accuracy Temp/Pressure/Humidity sensor) to push to an MQTT broker. Or if you prefer some sample code in micropython to do the same. The combined cost for both components can be as little as $10 depending on the knock off on amazon. Or ~$30 for legit items from Adafruit.

shameless self promotion, I have been working on this to provide multi room/zone monitoring for fairly cheap using raspberry pi's and DHT22 sensors https://github.com/the-amaya/sysTAMI
