I bought the ORIA Digital Hygrometer Thermometer Display from Lazada when they are having a flash sale.
I got it for S$9.20 with free shipping to Singapore. The usual price is S$11.15.
This device can support a temperature ranging from -10°C to 50°C with a temperature accuracy of ±1°C.
For humidity, it supports a range of 10% to 99% and has an accuracy of ±5%.
Two AAA batteries are needed to power this display, and sadly they are not included in the packaging.
The readings are large and clear and have additional minimum and maximum readings for the day to the right of the current readings.
I am using Atmotube Pro to benchmark against the temperature and humidity reading. The temperature differs by 0.9°C, with Atmotube Pro being higher and for humidity, the difference is 2%, with Atmotube Pro being lower.
